Assertion `:` The images formed by total internal reflections are much brighter than those formed by mirrors or lenses.
Reason `:` There is no loss of intensity in total internal reflection.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true and reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
In total internal reflection, 100 % of incident light is reflected back into the same medium, and there is no loss of intensity, while in reflection from mirrors and refractioni from lenses, there is always some loss of intensity. Therefore images formed by total internal reflection are much brighter than those formed by mirrors or lenses.

Assertion : The images formed by total internal reflections are much brighter than those formed by mirrorrs or lenses. Reason : There is no loss of intensity in total internal reflection.

Assertion:- Images formed by TIR (Total internal reflection) are much brighter than formed by mirrors or lenses. Reason:- IN TIR, there is no loss of intensity while in case of reflection from mirrors or refraction from plane surfaces or lenses there is some loss of intensity as all light can never be reflected or refracted.
