Central (GMT â 6 hours) Saskatchewan, province of Canada, one of the Prairie Provinces. It is one of only two Canadian provinces without a saltwater coast, and it is the only province whose boundaries are all wholly artificial (i.e., not formed by natural features).
A diffraction grating is a optical material or device that is usually designed to break up white light into the various colors of the visible spectrum.laze angles are used to concentrate a diffraction grating output on a certain band region of the light spectrum. This is done to obtain a maximum resolution in a particular band of light known as the Blaze wavelength.
difÂ·fracÂ·tion. The bending or turning of a wave, such as a light wave, when it encounters an obstacle, such as an edge, or a hole whose size is similar to the wavelength of the wave. The patterns made by the diffraction of waves can be useful for understanding the minute structures of objects.. 1. (General Physics) physics a deviation in the direction of a wave at the edge of an obstacle in its path. 2. (General Physics) any phenomenon caused by diffraction and interference of light, such as the formation of light and dark fringes by the passage of light through a small aperture.
