A ray of light is travelling through a medium of refractive index 1 2 with respect to air. When it is incident on the surface making an angle 45^ with the surface, which of the following will take place?

Step-by-step solution

Given, = 1 2 w.r.t. air i=45^ , r= ? Also, = i r 1 2 = 45^ r 1 2 = 1 / 2 r aligned & & r & =1 & & r & =90^ aligned Note that the ray is incident from denser medium and is refracted into a rarer medium air.
