JEE · NEET Previous Year Question
Given below are two statements : one is labelled as Assertion (A) and the other is labelled as
Reason (R).
Assertion-(A): If Young's double slit experiment is performed in an optically denser medium than air, then the consecutive fringes come closer.
Reason-(R): The speed of light reduces in an optically denser medium than air while its frequency does not change.
choose the most appropriate answer from the options given below:
