Critical Angle|Total Internal Reflection|Conditions For Total Internal Reflection|Questions

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.

Define critical angle for total internal reflection and write its relation with refractive index.

If the critical angle for total internal reflection from a medium to vacuum is 45^@ , then velocity of light int he medium is,
