Answer 2

Answer:

here you go..

Explanation:

1. Refraction of light.

2. a. The incident ray refracted ray, and the normal to the interface of two media at the point of incidence all lie on the same plane.

   b.   The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. This is also known as Snell’s law of refraction.

          sin i/sin r=constant
