Question

a ray of light is incident at an angle of 45 degree .will the light of refraction be more,less or equal to 45 degree?

Answer 1

The refracted angle will be less

Answer 2

Answer:

The angle of refraction will be either more or less .

Explanation:

When the ray of light refracts into a denser medium (Optically Denser medium), then the angle of refraction will be less compared to angle of incidence. But, when the ray of light refracts into a less dense medium (Optically Rarer Medium), the angle of refraction will be more than the angle of incidence .

Therefore, A refracted ray can either have a more or less angle compared to the angle of incidence .
