Question: Which of the following statements about circularly polarized light is true?

Options:

1. It has no preferred direction of oscillation
2. It oscillates in a single plane
3. It can be converted to linearly polarized light
4. It is always produced by reflection

Correct Answer: It has no preferred direction of oscillation

Solution:

Circularly polarized light has no preferred direction of oscillation; the electric field vector rotates in a circular motion.
