JEE Main 2025 — Ray Optics Question with Solution
JEE Main 2025 (7 Apr Shift 2)
Question
Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R)
Assertion (A) : Refractive index of glass is higher than that of air.
Reason ( ) : Optical density of a medium is directly proportionate to its mass density which results in a proportionate refractive index.
In the light of the above statements, choose the most appropriate answer from the options given below :
Assertion (A) : Refractive index of glass is higher than that of air.
Reason ( ) : Optical density of a medium is directly proportionate to its mass density which results in a proportionate refractive index.

Correct answer
C is correct but is not correct
Step-by-step explanation
Refractive index has no relation with mass density because both have different meaning. Hence reason is incorrect.
So (A) is correct but (R) is not correct.
So (A) is correct but (R) is not correct.
