Sentence examples for extraordinary rays from inspiring English sources

The Wollaston analyzer splits images of the ordinary and extraordinary rays by 5°.

In the direct image mode of the instrument, instead of the spectra I o and I e, images of the comet obtained in ordinary and extraordinary rays are used.

A dichroic substance such as tourmaline transmits only the extraordinary ray, having absorbed the ordinary ray (see illustration).

The echoes of the extraordinary ray are not available owing to the absence of the strong magnetic field on Mars.

In double refraction, the ordinary ray and the extraordinary ray are polarized in planes vibrating at right angles to each other.

One ray (called the extraordinary ray) is bent, or refracted, at an angle as it travels through the medium; the other ray (called the ordinary ray) passes through the medium unchanged.

Because the speed of light waves in a medium is equal to their speed in a vacuum divided by the index of refraction for that wavelength, an extraordinary ray can move either faster or slower than an ordinary ray.

When ordinary light is incident on a crystal exhibiting double refraction, the light is split into two polarized components, an ordinary ray and an extraordinary ray, vibrating in mutually perpendicular planes.

An incident ray is seen to split into the ordinary ray CO and the extraordinary ray CE upon entering the crystal face at C. If the incident ray enters the crystal along the direction of its optic axis, however, the light ray will not become divided.

When a ray of unpolarized (ordinary) light falls on a dichroic uniaxial crystal, any given wavelength will be absorbed differently according to which plane it is vibrating in, except along the optic axis for which there is no distinction between an ordinary ray and an extraordinary ray.

Furthermore, the refractive index (a number that determines the angle of bending specific for each medium) of the ordinary ray is observed to be constant in all directions; the refractive index of the extraordinary ray varies according to the direction taken because it has components that are both parallel and perpendicular to the crystal's optic axis.
