Although traditionally considered one of seven colors of the rainbow or the optical spectrum, modern color scientists do not usually recognize indigo as a separate division and generally classify wavelengths shorter than about 450 nm as violet.

Although the aether is almost stationary according to Fresnel, his theory predicts a positive outcome of aether drift experiments only to second order in, because Fresnel's dragging coefficient would cause a negative outcome of all optical experiments capable of measuring effects to first order in.

Although these nebulae have different visibility at optical wavelengths, they are all bright sources of infrared emission, chiefly from dust within the nebulae.

Although much of the optical and X-ray emission from supernova remnants originates from ionized gas, a great amount of the radio emission is a form of non-thermal emission called synchrotron emission.

Although it does handle interreflection and optical effects such as refraction accurately, traditional ray tracing is also not necessarily photorealistic.

Although energy generated by stimulated emission is always at the exact frequency of the field which has stimulated it, the above rate equation refers only to excitation at the particular optical frequency corresponding to the energy of the transition.

Although the electronic transitions of an isolated ion are very well defined, broadening of the energy levels occurs when the ions are incorporated into the glass of the optical fiber and thus the amplification window is also broadened.

Although the optical sound should have been inferior in quality to magnetic sound ( running at 3. 6 inches per second for 24 frames per second ), in practice it was often much better, largely because packaged movie magnetic sound was often poorly recorded.

Although the term commonly refers to wireless data transfer mechanisms ( e. g. using radio, hypersonic or infrared systems ), it also encompasses data transferred over other media such as a telephone or computer network, optical link or other wired communications like phase line carriers.

Although these late paintings appear to be ' impressionistic ' and therefore a forerunner of the French school, Turner was striving for expression of spirituality in the world, rather than responding primarily to optical phenomena.

Although seeing in the infrared, the UKIRT was large for an optical telescopes and signaled a coming focus on this part of the spectrum that only grew in the coming decades.

Although Digges may have created a rudimentary instrument involving lenses and mirrors, the optical performance required to see the details of coins lying about in fields, or private activities seven miles away, was far beyond the technology of the time.

Although his initial laboratory measurements of closure phase had been done at optical wavelengths, he foresaw greater potential for his technique in radio interferometry.

Although an oblique font can be generated by simply tilting the base font, some designers use optical correction to correct the distorted curves this introduces.

Although reflecting telescopes produce other types of optical aberrations, it is a design that allows for very large diameter objectives.

Although this means that it is not possible to focus the beams nearly as tightly as for light, it also means that the aperture or " capture area " of even the simplest, omni-directional antenna is greatly larger than that of a lens in any feasible optical system.

Although early developers and users of distributions built on top of the Linux kernel could take advantage of cheap optical disks and rapidly declining prices of CD drives for personal computers, the Linux distribution CDs or " distros " were generally treated as a collection of installation packages that must first be permanently installed to hard disks on the target machine.

Although some live CDs can load into memory to free the optical drive for other uses, loading the data from a CD-ROM is still slower than a typical hard drive boot, so this is rarely the default with large live CD images, but for smaller live CD images loading the filesystem directly into RAM can be highly practical.

Although optical alarms are highly effective at detecting smoldering fires and do provide adequate protection from flaming fires, fire safety experts and the National Fire Protection Agency recommend installing what are called combination alarms, which are alarms that either detect both heat and smoke, or use both the ionization and photoelectric / optical processes.

Although optical, they appear as hard disk drives to the operating system and do not require a special filesystem ; they can be formatted as FAT, HPFS, NTFS, etc.

Although a few astrophysicists still argue in favor of this view, most believe that apparent velocities greater than the velocity of light are optical illusions and involve no physics incompatible with the theory of special relativity.

Although in theory baseline-free, both modulation techniques are usually limited by residual amplitude modulation ( RAM ), either from the laser or from multiple reflections in the optical system ( etalon effects ).

Although the above equations were derived using simplifying assumptions, the implications are clear ; the energy of the quantum dots are dependent on their size due to the quantum confinement effects, which dominate below the critical size leading to changes in the optical properties.

Although programs can alter the position of the screen in memory, the non-linear format of the display means that vertical scrolling can only be done in blocks of 8 pixels without further work.

Although most audio file formats support only one type of audio data ( created with an audio coder ), a multimedia container format ( as Matroska or AVI ) may support multiple types of audio and video data.

Although the format now supports many audio encoding formats, it remains associated with the µ-law logarithmic encoding.

Although each country has made its own adaptations and changes to the format, the contestants are confined to a specially designed house where their every action is recorded by cameras and microphones at all times and they are not permitted to make any contact with the outside world.

Although the content of the document file is arranged in a format that the word-processing program understands, the user is able to choose the name and location of the file and provide the bulk of the information ( such as words and text ) that will be stored in the file.

Although its file format also allows for multiple such streams to be concatenated ( zipped files are simply decompressed concatenated as if they were originally one file ), gzip is normally used to compress just single files.

Although its use is not recommended for compatibility reasons, nevertheless much premastered material is produced in the format.

Although the origins of music videos go back much further, they came into their own in the 1980s, when Music Television's format was based on them.

Although these innovations are not all entirely new with Wadzinski, the book marks a significant advancement in published maze puzzles, offering expansions on the traditional puzzles that seem to have been fully informed by various video game innovations and designs, and adds new levels of challenge and complexity in both the design and the goals offered to the puzzle-solver in a printed format.

Although the show returned for the 1958 – 1959 season ( 5: 30 to 6: 00 pm ET ), these programs were repeats from the first two seasons, re-cut into a half-hour format.

Although the music in general did not meet the criteria for progressive rock, some songs adopted a dynamic format.

Although not directly comparable to SVG since it is a bitmap-based format, the Canvas element in HTML5 provides an approach to rendering dynamic graphics in HTML that is procedural rather than declarative: instead of specifying the shapes to draw in XML, the author executes drawing commands from a script.

Although generally skeptical of 3-D film as a format, Herzog premiered the film at the 2010 Toronto International Film Festival in 3-D and had its European premiere at the 2011 Berlinale.

Although the first design was patented as early as 1908, the first commercial 35 mm camera was the 1913 Tourist Multiple, for movie and still photography, soon followed by the Simplex providing selection between full and half frame format.

Although never as popular as Super 8, the format existed in parallel.

Although the 8 mm format was originally intended for creating amateur films, condensed versions of popular cinema releases were available up until the mid 1980s, for projection at home.

Although primarily targeted at XML documents, xml: tm can be used on any document that can be converted to XLIFF format.

Although there were other magnetic tape cartridge systems, the Compact Cassette became dominant as a result of Philips ' decision in the face of pressure from Sony to license the format free of charge.

Although intended as a replacement for audio cassettes, the format was never widely adopted by consumers because of issues of expense and concerns from the music industry about unauthorized digital quality copies.

Although the show — a repackaging of somewhat dated British video game review shows ( mostly Gamer. tv )— was short-lived, it was a sign of the network's change of format from Game Show Network's " all game shows, all the time " to what eventually became " GSN: The Network for Games ".

Although there are some differences in the format of the Anında Görüntü Show, it is still very close to the original Whose Line Is It Anyway ?.

Although the AmigaGuide format is almost solely used for documenting Amiga programs, viewers are available for several other platforms:

Although the origins of music videos date back much further, they came into prominence in the 1980s, when MTV based their format around the medium.

Although now part of Greater London, almost all postal addresses used in any format, ( letter, online address etc.

Although it is implied that nuclear warfare has destroyed humanity, film critic Andrew Sarris notes that the episode's necessarily unrealistic format may have been what allowed its production to commence:
