Question

Assertion: Total internal reflection occurs when the rays of light strike at an angle less than the critical angle.

Reason: There is no absorption of light during total internal reflection.

Options

• If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

• If both Assertion and Reason are true, but Reason is not correct explanation of the Assertion.

• If Assertion is true, but the Reason is false.

• If Assertion is false, but the Reason is true.

Answer 1

If Assertion is false, but the Reason is true.

Explanation:

Total internal reflection occurs only when light strikes the interface from a denser to a rarer medium at an angle greater than the critical angle ($$i > C$$). The assertion is false, but the reason that 100% of the light is reflected without absorption is true.
