An apparatus similar to the one used in diffraction grating experiment is used to measure ruling density of a diffraction grating. A second order maximum is observed to be 1.463 m from the central maximum. The wavelength of the coherent, monochromatic light striking the grating is 501 nm. The distance from the double slit to the display screen is 2.09 m.
