Question

Q.2 Why does the light change its direction in the refractive medium in refraction on its oblique incidence? Does it
changes its direction on perpendicular incidence?​

Answer 1

Answer:

Nice question mate !!!

Any refraction that take place should follow the huygen's principle Always satisfying the equation μsinΘ = const

Hence on some certain angle in denser medium the light undergoes TIR phenomena. Hence it reverse its direction.

On perpendicular incidence since Θ = 0 the light will not suffer any change in its direction. So it do not change its direction.

Hope this helps !!!
