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? (hint: the largest m when q = 90°)
b) what is the angle formed by the first-order bright spot and the central maximum?
c) how far apart on the screen are the first-order and second-order maxima on the same side of the central maximum?
