Question

What is snells law explain

Answer 1

Hi ,


According to the Snell's law,

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

Sine of angle of incidence(i)/sine of angle of refraction(r)=constant

This constant is called refractive index(n).

n=sin i/sin r

Hope , this helps .......

Answer 2

When a ray of light passes through a medium to another medium,it undergoes refraction.It states that the ratio of sine of angle of incidence to sine of angle of refraction is a constant.
