Question

Unpolarized light is incident from air
on a plane surface of a material of
refractive index ' '  . At a particular
angle of incidence i, it is found that
the reflected and refracted rays are
perpendicular to each other. Which of
the following option is correct for this
situation.

Answer 1

When Unpolarized light is incident from air  on a plane surface of a material of  refractive index n ,

• The Electric field vector will be 90 with incident ray

• The angle made is Brewster's angle
• n = tan i
