उत्तर

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.
