he diffraction grating is a way of separating or dispersing light of different wavelengths, producing a spectrum of light. The grating interferes light constructively in particular directions: dsinθm=mλdsin⁡θm=mλ For a particular angle, we calculate the wavelength. The grating constant (or line density) is 500 lines per mm -- every millimeter has 500 lines scratched onto it, equally spaced. The quantity d is the distance between the lines, and λ is the light wavelength. A meter stick shows the spots, and ym is position on the meter stick of the mth-order light beam. (Negative order is the same as positive order.) Calculate the light wavelength, λ in nm, given this information: The grating constant is 500 lines/mm. L = 31.5 cm y1 = 56.9 cm y-1 = 40.8 cm y0 isn't specified because of computer issues. (It's the average of y1 and y-1.)

Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.
