As the angle of incidence increases what happens to the amount the light refracts?

The light will refract to a greater angle but refraction occurs at the extent when the angle of incidence is less than the critical angle

Explanation:

The angle of incidence is directly proportional to the angle of refraction. This can also be seen from the Snell's law as:

Using Snell's law as:

Where,  

 is the angle of incidence

is the angle of refraction

is the refractive index of the refraction medium

is the refractive index of the incidence medium

It can be seen from the formula also that as the angle of incidence increase, the angle of refraction also increases.

However, if the angle of incidence increases beyond the critical angle, reflection of the light occur instead of the refraction.
