Question

State the 2 laws of refraction

Answer 1

Answer:

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.

Explanation:

Please mark me as brainliest answer

Answer 2

Answer:

1 - incident ray ,refraction ray

and normal lie on the same plane.

2- the ratio of sin of angle of incident is equal to sine of angle of refraction.

sin i/sin r =constant

second law of refraction also known as Snell's law.
