NEET Physics (general) Assertion Reason Question
Assertion (A): A lens with the same refractive index as the surrounding medium will not converge or diverge light. | Reason (R): The refractive index of the lens must be equal to the refractive index of the medium for the lens to act like a plane sheet of glass.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
