Diffraction Grating. A diffraction grating is the tool of choice for separating the colors in incident light. This illustration is qualitative and intended mainly to show the clear separation of the wavelengths of light. There are multiple orders of the peaks associated with the interference of light through the multiple slits.
A typical diffraction grating consists of a substrate, usually of an “optical material”, with a large number of parallel grooves ruled or replicated in its surface and overcoated with a reflecting material such as aluminum.
“The diffraction grating is a useful device for analyzing light consists of a large number of equally spaced parallel slits.”Its working principle is based on the phenomenon of space between lines act as slits and these slits diffract the light waves thereby producing a large number of beams which interfere in such a way to produce spectra.
Diffraction is the spreading out of waves as they pass through an aperture or around objects. It occurs significantly when the size of the aperture or obstacle is of similar linear dimensions to the wavelength of the incident wave.

This diffraction grating calculator will help you find out what happens when the light hits a structure with multiple openings (slits or rulings). The light ray gets diffracted in various directions. Our tool determines the paths that light takes with the use of a simple diffraction grating formula.
In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams travelling in different directions. The emerging coloration is a form of structural coloration. The directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element.
A diffraction grating is a large collection of evenly spaced parallel slits that produces an interference pattern similar to but sharper than that of a double slit. There is constructive interference for a diffraction grating when , where is the distance between slits in the grating, is the wavelength of light, and is the order of the maximum.
The well-known diffraction grating equation can be represented by a simple and useful graph that makes the analysis of the diffraction orders produced by a grating easier. This paper explains the construction of the graph and how to use it with an example.
Diffraction by a grating can be visualized from the geometry in Figure 2-1, which shows a light ray of wavelength λ incident at an angle α and diffracted by a grating (of groove spacing d, also called the pitch) along angles βm. These angles are measured from the grating normal, which is the dashed

The spectrometer apparatus takes advantage of the fact that the wavelength ( \(\lambda\)) of Sodium light is diffracted from a straight path by the small openings in the diffraction grating, and the relationship between the size of the grating, the wavelength of light, and the angle of diffraction follows a known equation. Then:

Diffraction from a three-dimensional periodic structure such as atoms in a crystal is called Bragg diffraction. It is similar to what occurs when waves are scattered from a diffraction grating. Bragg diffraction is a consequence of interference between waves reflecting from different crystal planes.
Atomic hydrogen emits two waves whose wavelengths are 656 and 410 nm. The waves fall on a grating that has 5310 lines/cm. What is the angular separation theta656- theta410, of the waves in the second-order maximum? Or The wavelengths of the laser beam used in a compact disc player is 790 nm. Suppose that a diffraction grating produces first-order tracking beams that are mm apart at a
