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

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