Consider Two Diffraction Gratings with the Same Slit Separation, the Only

Multiple Choice

Consider two diffraction gratings with the same slit separation, the only difference being that one grating has 3 slits and the other 4 slits. If both gratings are illuminated with a beam of the same monochromatic light, make a statement concerning the separation between the orders.

A) The grating with 3 slits produces the greater separation between orders.
B) The grating with 4 slits produces the greater separation between orders.
C) Both gratings produce the same separation between orders.
D) Both gratings produce the same separation between orders, but the orders are better defined with the 4-slit grating.
