Question

A Ray of light incident at 60 degree on glass air interface then the light Ray will
a. refracts at 30°
b.reflect back into glass
c.refracts at 90°
d.none of these

plz do it in steps

Answer 1

reflect back into glass

Answer 2

Here in this situation, both conditions of total internal refraction are satisfied as:-

Light Ray is traveling from denser(glass) to rarer( air).The angle of incidence ( in denser medium) is greater than the critical angle for glass- air inference (~ 42°). Here in this case angle of incidence is 60°.

So, light rays refract back to glass.
