  • Assertion (A) : The images formed by total internal reflections are much brighter than images formed by mirrors or lenses. Reason (R ) : There is no loss of intensity in total internal reflection.

    A
    If both assertion and reason are true and the reason is the correct explanation of the assertion.
    B
    If both assertion and reason are true but reason is not the correct explanation of the assertion.
    C
    If assertion is true but reason is false.
    D
    If the assertion is false but reason is true.

  • 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.

    A
    If both Assertion `&` Reason are True `&` the Reason is a correct explanation of the Assertion.
    B
    If both Assertion `&` Reason are True but Reason is not a correct explanation of the Assertion.
    C
    If Assertion is True but the Reason is False.
    D
    If both Assertion `&` Reason are False.
