egg Home Expert QLA My solutions dent question Time Left: 01:55:32 1) If a laser beam of wavelength 4.0e+02 nm is sent through a diffraction grating of 250 lines per mm, at what angle will the first-order maximum be? degrees 2) You send a laser beam of wavelength 550 nm through a diffraction grating. You note that the first-order maximum is at 5.0\deg from the straight-through direction. What is d, the spacing between slits of the grating? How many slits are there, per millimeter? please answer both parts, thanks in advance!
