Question

Explain fermat principle with diagrams.​

Answer 1

Explanation:

We can make several observations as a result of Fermat’s Principle which will prove useful as we explore the realm of geometric optics:

In a homogeneous medium, light rays are rectilinear. That is, in any medium where the index of refraction is constant, light travels in a straight line.

The angle of reflection of a surface is equal to the angle of incidence. This is the Law of Reflection.
