Unpolarised light is incident from air on a plane surface of a material of refractive index 
. At a particular angle ofincidence i , it is found that the reflected and refracted rays are perpendicular to each other. Which of the following options is correct for this situation7.
A
Reflected light is polarised with its electric vector parallel to the plane of incidence
B
Reflected light is polarised with its electric vector perpendicular to the plane of incidence
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
: When reflected light and refracted light are perpendicular, reflected light is polarised with electric field vector perpendicular to the plane of incidence.
Also,
