Question

A laser with a wavelength of 532 nm is aimed horizontally at a diffraction grating with 580 grooves per mm in a large, dark room. The grooves are oriented vertically. The laser is 2.7 m away from the diffraction grating, while a flat, white wall is 3.9 m behind the diffraction grating. Describe what appears on the wall and where.

Answer 1

The diffraction will occur due to the grating. Using the standard equation we can find the maxima of diffraction as follows.
