Analyzing +4 | -1

Assertion (A): In Snell's law

\mu=\frac{\sin i}{\sin r}

, angle

i

is always angle of incidence.

Reason (R):

\mu=\frac{\sin i}{\sin r}

is applicable one medium in air (or vacuum).

View answer and explanation

Correct option: C

If assertion is true but reason is false.

Option C is correct. The assertion is true because the refractive index is defined as the ratio of the sine of the angle of incidence to the sine of the angle of refraction. The reason is false because Snell's law applies to any pair of media, not just air or vacuum.
