Question

What are the 3 laws of refraction?

Answer 1

Explanation:

Laws of Refraction

The incident ray, the refracted ray and the normal to the surface at the point of incidence all lie in one plane.

For any two given pair of media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.

The above law is called Snell's law after the scientist Willebrod Snellius who first formulated it.

Answer 2

Laws Of Refraction :-

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

• 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.

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