Which of two diffraction gratings,one with N₁ and the other with N₂ slits per centimeter,has the greater resolving power if N₁ is greater than N₂? A)the grating with N₁ slits per centimeter B)the grating with N₂ slits per centimeter C)They both have the same resolving power,but the one with N₁ slits per centimeter has sharper spectral lines. D)They both have the same resolving power,but the one with N₂ slits per centimeter has sharper spectral lines. E)The width of the individual slits must be known to answer this question.

Question

Quizplus · Accepted Answer

The resolving power of a diffraction grating increases with the number of slits per centimeter. Therefore, the grating with more slits per centimeter (N₁) has greater resolving power.
