Question

How does a diffraction pattern produced by a diffraction grating generally compare to that produced by a Young's double-slit experiment?
Options
A It is less bright and less sharp.
B It is brighter and less sharp.
C It is less bright and sharper.
D It is brighter and sharper.
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

The text states, 'If many parallel slits similar to those in Young's experiment are spaced regularly and of the same width, a brighter and sharper diffraction pattern can be obtained.'

Hint

The first paragraph under 'Diffraction grating' explains the advantage of a grating over a double-slit.
