Question

state and explain laws of refraction for class 9​

Answer 1

Explanation:

Laws of refraction state that: The incident ray, reflected ray and the normal, to the interface of any two given mediums, all lie in the same plane. The ratio of the sine of the angle of incidence and sine of the angle of refraction is constant. This is also known as Snell's law of refraction.
