Question

How does the diffraction pattern produced by a diffraction grating compare to that produced by a double-slit setup, as stated in the text?
Options
A The grating pattern is dimmer and wider.
B The grating pattern is brighter and sharper.
Correct Answer
C The grating pattern has fewer interference fringes.
D The grating pattern only produces dark fringes.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 5 mentions: 'If many parallel slits...a brighter and sharper diffraction pattern can be obtained' when referring to a diffraction grating.

Hint

The advantage of using a diffraction grating over a double-slit setup is highlighted in its introduction.
