Question

Assertion (A): When a ray of light passes from one medium to another medium, its frequency changes.

Reason (R): The frequency of light depends on the source of light.

पर्याय

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).

• Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).

• Assertion (A) is false, but Reason (R) is true.

• Assertion (A) is true, but Reason (R) is false.

Answer 1

Assertion (A) is false, but Reason (R) is true.

Explanation:

Assertion (A) is false because the frequency of light remains unchanged when it passes into another medium. Reason (R) is true because the frequency is determined by the source of light.
