The technology of manipulating electron beams pioneered in Crookes tubes was applied practically in the design of vacuum tubes, and particularly in the invention of the cathode ray tube by Ferdinand Braun in 1897.

It consists of the nephrons grouped around a single medullary ray, and draining into a single collecting duct

In path tracing, however, only a single ray or none is fired at each intersection, utilizing the statistical nature of Monte Carlo experiments.

This method continued even when cathode ray tubes were manufactured as rounded rectangles ; it had the advantage of being a single number specifying the size, and was not confusing when the aspect ratio was universally 4: 3.

The incident and reflected rays and the normal lie in a single plane, and the angle between the reflected ray and the surface normal is the same as that between the incident ray and the normal.

In fiber-optic communication, a single-mode optical fiber ( SMF ) ( monomode optical fiber, single-mode optical waveguide, or unimode fiber ) is an optical fiber designed to carry only a single ray of light ( mode ).

This is the case in single-mode fibers, where we can have waves with different frequencies, but of the same mode, which means that they are distributed in space in the same way, and that gives us a single ray of light.

This forbids the creation of a single gamma ray.

Each ray floret is anatomically an individual flower with a single large petal.

A single ray of light shines out and lands precisely on the old man's eye, revealing that it is wide open.

The pelvic fins of juveniles have up to 10 rays, but in adults this is reduced to a single elongated ray at the throat.

The emitted 159 keV gamma ray is used in single photon emission computed tomography ( SPECT ).

This method continued even when cathode ray tubes were manufactured as rounded rectangles ; it had the advantage of being a single number specifying the size, and was not confusing when the aspect ratio was universally 4: 3.

In order to draw the world, a single ray is traced for every column of screen pixels and a vertical slice of wall texture is selected and scaled according to where in the world the ray hits a wall and how far it travels before doing so.

By contrast, in internal conversion, as noted, no gamma ray is emitted at all and the electron energy is fixed at a single, typical value.

Notice that this complex set of five deflections above looks exactly like a single deflection, as shown by ray 2 at left.

Its companion is Khabs Am Pekht, which in the Egyptian language means roughly " Light in extension " or " Light rushing out in a single ray ", is used in the Hermetic Order of the Golden Dawn's Vernal and Autumnal Equinox ceremonies.

Continuing earlier studies of Keith Lucas, he used a capillary electrometer and cathode ray tube to amplify the signals produced by the nervous system and was able to record the electrical discharge of single nerve fibres under physical stimulus.

For simplicity, " reflections " are spoken of here, but more generally the interface between the small particles that constitute many materials is irregular on a scale comparable with light wavelength, so diffuse light is generated at each interface, rather than a single reflected ray, but the story can be told the same way.

Specular reflection is the mirror-like reflection of light ( or of other kinds of wave ) from a surface, in which light from a single incoming direction ( a ray ) is reflected into a single outgoing direction.

The incident and reflected rays lie in a single plane, and the angle between the reflected ray and the surface normal is the same as that between the incident ray and the normal.

The word-element " radio -" in the title originates from the combining form of Latin radius, a ray.

He believed that this new force was a form of electricity in addition to the " natural " form produced by lightning or by the electric eel and torpedo ray as well as the " artificial " form produced by friction ( i. e., static electricity ).

Upon its suicide by way of a disintegration ray, the Phoenix Force disperses into its original form and a fragment locates the still-healing Jean at the bottom of Jamaica Bay.

It is also possible to produce polarised light rays using a combination of reflection and refraction: When a refracted ray and the reflected ray form a right angle, the reflected ray has the property of " plane polarization ".

Contemporary scanners can estimate attenuation using integrated x-ray CT equipment, however earlier equipment offered a crude form of CT using a gamma ray ( positron emitting ) source and the PET detectors.

The nucleus of a metastable isotope is in an excited state and will return to the ground state by emitting a photon in the form of a gamma ray.

To see this, the three corresponding normal vectors of the corner's perpendicular sides can be considered to form a basis ( a rectangular coordinate system ) ( x, y, z ) in which to represent the direction of an arbitrary incoming ray, b, c. When the ray reflects from the first side, say x, the ray's x component, a, is reversed to-a while the y and z components are unchanged, resulting in a direction of b, c. Similarly, when reflected from side y and finally from side z, the b and c components are reversed.

The Mössbauer effect is the resonant and recoil-free emission and absorption of gamma ray photons by atoms bound in a solid form.

Carbon and oxygen nuclei collide with interstellar matter to form lithium, beryllium and boron in a process termed cosmic ray spallation.

* Arthur Appel, American computer scientist and author, presented the first algorithm for ray casting as a form of image rendering

For example, the mass of an atomic nucleus is less than the total mass of the protons and neutrons that make it up, but this is only true after this energy from binding has been removed in the form of a gamma ray ( which in this system, carries away the mass of the energy of binding ).

While the proposal for Phoenix was being written, the Mars Odyssey Orbiter used its gamma ray spectrometer and found the distinctive signature of hydrogen on some areas of the Martian surface, and the only plausible source of hydrogen on Mars would be water in the form of ice, frozen below the surface.

The first Klingon ship design used in The Original Series, the D7-class battlecruiser, was designed by Matt Jefferies to evoke a shape akin to that of a manta ray, providing a threatening and instantly recognizable form for viewers.

They form heads or capitula in panicles of yellow, brown or purple flowers in ray florets.

The inflorescence is 2. 5 – 5 cm diameter, pink-purple, with all the florets of similar form ( no division into disc and ray florets ).

The data is interpolated at each sample point, the transfer function applied to form an RGBA sample, the sample is composited onto the accumulated RGBA of the ray, and the process repeated until the ray exits the volume.

It is also possible to produce polarized light rays using a combination of reflection and refraction: When a refracted ray and the reflected ray form a right angle, the reflected ray has the property of " plane polarization ".
