Question

state the laws of refraction of light explain the term abs absolute Refractive Index of a medium and write an expression to relate it with the speed of light in vacuum​

Answer 1

Answer:

Explanation:

1 . Laws of reflection are valid for

smooth surfaces like mirror.

2 . The incident ray, Normal and reflected ray all lie in same plane.

3 . Angle of incidence is always equal to angle of angle of reflection.
