Total internal reflection may be observed if

Will total internal ,reflection take place when light passing through water is incident on the surface of separation with air at the angle of incidence of 45^@ ? Why ?

Write whether the following statement are true or false. If false, correct the statement Total internal reflection is possible only when the angle of incidence is greater than the critical angle.

Based on refraction and total internal reflection explain the formation of rainbow.
