Question

What is a diffraction grating, as described in the document?
Options
A A single narrow slit that causes diffraction.
B A material that blocks all light wavelengths.
C An arrangement of many parallel slits spaced regularly to produce a sharper diffraction pattern.
Correct Answer
D A filter used to polarize light.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 5 defines a diffraction grating: '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. Such an arrangement is known as a diffraction grating.'

Hint

Look for the definition of 'Diffraction grating' at the beginning of that section.
