These pigments are named after the wavelength ( in nanometers ) of their red-peak absorption maximum.

When the two waves are in phase, i. e. the path difference is equal to an integral number of wavelengths, the summed amplitude, and therefore the summed intensity is maximum, and when they are in anti-phase, i. e. the path difference is equal to half a wavelength, one and a half wavelengths, etc., then the two waves cancel and the summed intensity is zero.

Black body radiation is radiation from an idealized radiator that emits at any temperature the maximum possible amount of radiation at any given wavelength.

A black body will also absorb the maximum possible incident radiation at any given wavelength.

As the wave slows down, the wavelength gets shorter and the amplitude increases ; after a place of maximum response, the short wavelength is associated with a high loss and the wave dies out.

In fiber optics, it is more common to consider the cutoff wavelength, the maximum wavelength that will propagate in an optical fiber or waveguide.

Peak wavelength is at 492 nm and the full width at half maximum | FWHM spectral bandwidth is quite wide at about 85 nm.

For instance, the colour of a dilute solution of copper sulfate is a very light blue ; adding ammonia intensifies the colour and changes the wavelength of maximum absorption ().

A peak of the absorbance curve ( a wavelength where the absorbance reaches a maximum ) is where the rate of change in absorbance with wavelength is smallest.

The commonly quoted parameters for phosphors are the wavelength of emission maximum ( in nanometers, or alternatively color temperature in kelvins for white blends ), the peak width ( in nanometers at 50 % of intensity ), and decay time ( in seconds ).

It can be seen that if such an element is resonant at f < sub > 0 </ sub > to produce such a standing wave pattern, then feeding that element with 3f < sub > 0 </ sub > ( whose wavelength is 1 / 3 that of f < sub > 0 </ sub >) will lead to a standing wave pattern in which the voltage is likewise a minimum at the feed-point ( and the current at a maximum there ).

To achieve the maximum gain, it is necessary that the shape of the dish be accurate within a small fraction of a wavelength, to ensure the waves from different parts of the antenna arrive at the focus in phase.

Applying the above formula to the 25-meter-diameter antennas often used in radio telescope arrays and satellite ground antennas at a wavelength of 21 cm ( 1. 42 GHz, a common radio astronomy frequency ), yields an approximate maximum gain of 140, 000 times or about 50 dBi ( decibels above the isotropic level ).

Theoretically, the maximum resolution, d, that one can obtain with a light microscope has been limited by the wavelength of the photons that are being used to probe the sample, λ and the numerical aperture of the system, NA.

DQDB is rated for a maximum of 160 km before significant signal degradation over fiberoptic cable with an optical wavelength of 1310 nm.

If the source has a maximum overall dimension or aperture width ( D ) that is large compared to the wavelength λ, the far-field region is commonly taken to exist at distances from the source, greater than Fresnel parameter S = D < sup > 2 </ sup >/( 4λ ), S > 1.

Again, this is true only in the far field, defined as: Range = 2 D < sup > 2 </ sup > / λ where D is the maximum linear extent of the optical sources and λ is the wavelength ( Scott ).

The most effective political inventions seem to make maximum use of natural harbors and are aware that restraining breakwaters can play only a minor part in the whole scheme.

The policy may not be unique but the maximum value of P certainly is, and once the policy is specified this maximum can be calculated by ( 2 ) and ( 3 ) as a function of the feed state Af.

`` We can claim on the maximum amount of the bond '', Berger said.

The maximum energy that an electrons can have at absolute zero is called the Fermi energy.

However, some systems have a maximum amount of energy that they can hold, and as they approach that maximum energy their entropy actually begins to decrease.

The time required is O ( log n ) for lookup, plus a maximum of O ( log n ) rotations on the way back to the root, so the operation can be completed in O ( log n ) time.

For example, if 95 % of the program can be parallelized, the theoretical maximum speedup using parallel computing would be 20 × as shown in the diagram, no matter how many processors are used.

For example, if for a given problem size a parallelized implementation of an algorithm can run 12 % of the algorithm's operations arbitrarily quickly ( while the remaining 88 % of the operations are not parallelizable ), Amdahl's law states that the maximum speedup of the parallelized version is times as fast as the non-parallelized implementation.

In the case of parallelization, Amdahl's law states that if P is the proportion of a program that can be made parallel ( i. e., benefit from parallelization ), and ( 1 − P ) is the proportion that cannot be parallelized ( remains serial ), then the maximum speedup that can be achieved by using N processors is

As an example, if P is 90 %, then ( 1 − P ) is 10 %, and the problem can be sped up by a maximum of a factor of 10, no matter how large the value of N used.

# VBR-Variable bit rate: an average or Sustainable Cell Rate ( SCR ) is specified, which can peak at a certain level, a PCR, for a maximum interval before being problematic.

Inductive coupling of the output can raise their efficiency to a maximum of 50 %.

A master Bluetooth device can communicate with a maximum of seven devices in a piconet ( an ad-hoc computer network using Bluetooth technology ), though not all devices reach this maximum.

An alternative view suggests that the optimum tension for power depends on the player: the faster and more accurately a player can swing their racquet, the higher the tension for maximum power.

In the BWF World Championships, first held in 1977, currently only the highest ranked 64 players in the world, and a maximum of four from each country, can participate in any category.

The fact that in equivalent baseband models of communication systems, the signal spectrum consists of both negative and positive frequencies, can lead to confusion about bandwidth, since they are sometimes referred to only by the positive half, and one will occasionally see expressions such as, where is the total bandwidth ( i. e. the maximum passband bandwidth of the carrier-modulated RF signal and the minimum passband bandwidth of the physical passband channel ), and is the positive bandwidth ( the baseband bandwidth of the equivalent channel model ).

* Some curves that seem simple, such as the circle, cannot be described exactly by a Bézier or piecewise Bézier curve ; though a four-piece cubic Bézier curve can approximate a circle ( see Bézier spline ), with a maximum radial error of less than one part in a thousand, when each inner control point ( or offline point ) is the distance horizontally or vertically from an outer control point on a unit circle.
