When he returmed to France he was given an administrative role in the French Army under the Duc de Broglie.

When the thermal de Broglie wavelength is much smaller than the interparticle distance, the gas can be considered to be a classical or Maxwell – Boltzmann gas.

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.

When light makes multiple reflections between two or more parallel surfaces, the multiple beams of light generally interfere with one another, resulting in net transmission and reflection amplitudes that depend on the light's wavelength.

When light strikes a material, most of the light is absorbed while a smaller amount of a particular frequency or wavelength is reflected.

When a beam of light crosses the boundary between a vacuum and another medium, or between two different media, the wavelength of the light changes, but the frequency remains constant.

When sodium or its compounds are introduced into a flame, they turn it yellow, because the excited 3s electrons of sodium emit a photon when they fall from 3p to 3s ; the wavelength of this photon corresponds to the D line at 589. 3 nm.

When wavelengths of electromagnetic radiation are quoted, the wavelength in vacuum usually is intended unless the wavelength is specifically identified as the wavelength in some other medium.

When a plane wave of wavelength λ with normal incidence, ( perpendicular to the grating ) each slit in the grating acts as a quasi point-source from which light propagates in all directions ( although this is typically limited to a hemisphere ).

When the path difference between the light from adjacent slits is equal to half the wavelength, λ / 2, the waves will all be out of phase, and thus will cancel each other to create points of minimum intensity.

When groove spacing is less than half the wavelength of light, the only present order is the m = 0 order.

When the photons belonging to the signal at a different wavelength from the pump light meet the excited erbium atoms, the erbium atoms give up some of their energy to the signal and return to their lower-energy state.

When the spectrum is reckoned per frequency interval, the Sun's peak emission appears at a frequency of 3. 43 x 10 < sup > 14 </ sup > Hz ; this means that the peak emission per unit frequency is at 3. 43 x 10 < sup > 14 </ sup > Hz, which corresponds to a wavelength of 883 nm and is well into the infrared.

When circularly polarized light passes through an absorbing optically active medium, the speeds between right and left polarizations differ ( c < sub > L </ sub > c < sub > R </ sub >) as well as their wavelength (< sub > L </ sub >< sub > R </ sub >) and the extent to which they are absorbed (< sub > L </ sub >< sub > R </ sub >).

When the wavelength of a gravity wave is less than twice the depth of the ocean or lake its behavior is governed by the nonlinear Schrodinger equation and its speed is proportional to.

When coherent light from the laser strikes a pit the material glows, giving off incoherent light of a different wavelength.

When this ratio is less than about one-tenth, Rayleigh scattering occurs in which the scattering coefficient varies inversely as the fourth power of the wavelength.

When an electron in the system absorbs a photon of light of the right wavelength, it can be promoted to a higher energy level.

When comparing the frequency and wavelength dependent expressions of the Rayleigh – Jeans law it is important to remember that

When the diameter of a particle is below or near the wavelength of light ( around 500 nanometers ), the particle cannot be seen in a light microscope with the usual method of illumination.

When a beam of neutrons emanating from a reactor is slowed down and selected properly by their speed, their wavelength lies near one angstrom ( 0. 1 nanometer ), the typical separation between atoms in a solid material.

When the size of the scattering center ( or grain boundary ) is reduced below the size of the wavelength of the light being scattered, the scattering no longer occurs to any significant extent.

When light strikes an object, it usually has not just a single frequency ( or wavelength ) but many.

When η has zero energy, like the infinite wavelength wave, it doesn't change at all.
