Answer
Assertion is false, but the Reason is true.
Explanation :
Assertion (A) is false : An vs. graph is not a straight line because Snell's law relates the sine of the angle of incidence to the sine of the angle of refraction not the angles themselves.
Reason (R) is true : Snell's Law is the law of refraction, it tells us how light bends when it passes from one medium to another.
