Question
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. Bother gratings produce the same separation between orders, but the orders are better defined with the 4-slit grating
B. The grating with 3 slits produces the greater separation between orders.
C. The grating with 4 slits produces the greater separation between orders.
D. Bother gratings produce the same separation between orders, but the orders are better defined with the 4 slit grating
Explanation / Answer
the correct answer is
D. Bother gratings produce the same separation between orders, but the orders are better defined with the 4 slit grating
