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, but the orders are better defined with the 3-slit grating..
D) Both gratings produce the same separation between orders, but the orders are better defined with the 4-slit grating.
