Consider an Experiment Using a Diffraction Grating with 7000 Lines/cm

Short Answer

Consider an experiment using a diffraction grating with 7000 lines/cm, a screen 2.50 m
away, and a 440- nm wavelength beam of light.
(a) How many side maxima will be observed on one side of the central maximum?
(b) How far apart on the screen are the first-order and second-order maxima on the same
side of the central maximum?
