उत्तर
Assertion is false, but the Reason is true.
Explanation:
The assertion is false because a graph of the angle of incidence versus the angle of refraction is not a straight line. Snell’s law states that the ratio of the sines of these angles is constant, which means a graph of sin i against sin r is a straight line. The reason is true.
