Conditions Of Total Internal Reflection

A ray of light strikes a glass plate at an angle of incidence 57^(@) . If the reflected and refracted rays are perpendicular to eachother, calculate critical angle for total internal reflection at glass air interface.

An optical fibre (mu = 1.72) is surrounded by a glass coating (mu= 1.50). Find the critical angle for total internal reflection at the fibre-glass interface.

Describe briefly any three applications of total internal reflection.

Define total internal reflection of light.
