VERY SHORT ANSWER AHEAD!!.....

Explanation:

When there is an increase in the critical angle of incidence , total internal reflection occurs there.

Increase on critical angle=total internal reflection.
This is also the same reason as due to the increase in the critical angle of angle of incidence of the light ray in the water drop total internal reflection occurs.
