Problem: Light from a laser strikes a diffraction grating that has 5 312 grooves per centimeter. The central and first-order principal maxima are separated by 0.488 m on a wall 1.90 m from the grating.

Part A- Determine the wavelength of the laser light.

I know the correct answer for above problem but explain how to get this answer! Thanks. In this problem, assume that the light is incident normally on the gratings.
