NEET Physics Refraction Assertion Reason Question
Assertion (A): The refractive index of a medium determines the angle of refraction when light passes from one medium to another. | Reason (R): Snell's law relates the sine of the angle of incidence to the sine of the angle of refraction, dependent on the refractive indices of the two media.
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.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The assertion and reason are both true; Snell's law (sin i/sin r = n21) directly involves the refractive indices and explains the angle of refraction.
