Answer 2

Because, light doesn't have any fixed time to pass any object. It wishes to rush in the shortest time from the medium A to the medium B. This is Know as the optics of particles the principal of least Action(Fermant's principal).

Fermant's Principal:-

A ray of light in passing from one point to another by any number of reflections or refractions chooses a path along which the time taken is the least or minimum.
