Question

What is critical angle and total internal reflection?

Short Note

Solution

  1. The angle of incidence in the denser medium for which the refracted ray graces the boundary is called critical angle ic.
  2. The entire light is reflected back into the denser medium itself. This phenomenon is called total internal reflection.
