Question
You send a laser beam of wavelength 463 nm through a diffraction grating, perpendicular to a screen. You note that the first-order maximum is located
30.1 cm from the central spot, the "zeroth-order maximum". The grating is 1.35 m from the screen.
What is d, the spacing between slits of the grating?
How many slits are there, per millimeter?
