Question

what is Refraction?state the laws of refraction.Draw the suitable ray diagram​

Answer 1

Answer:

Laws of refraction state that:

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. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.

Answer 2

Answer:

the fact or phenomenon of light, radio waves, etc. being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density is called refraction.

Explanation:

Laws :

1. The incident ray, the normal and the refracted ray at a point of incidence all lie in the same plane.

2. When a ray of light passes through a rarer medium to a denser medium, the refracted ray is closed to the normal while the ray of light passes through a denser medium to a rarer medium, the refracted ray is away from the normal. [for any two mediums, the ratio of the sine of angle of incidence to the angle of sine of refraction is constant which is called refractive index.]

3. An incident ray passing through the normal always goes straight.
