(i) The reflected beam is completely polarized. |
(ii) The refracted beam is partially polarized. |
(iii) The angle between the reflected and the refracted beams is \[{{90}^{o}}\]. |
A) (i) only
B) (ri) (ii)only
C) (i) and (iii)
D) All the statements are correct
Correct Answer: C
Solution :
According to the Brewsters theory the quantity of polarized light in reflected light depends upon angle of incidence. If angle of incidence is equal to a particular angle called polarizing angle \[({{i}_{p}})\] then reflected beam is completely polarized. Also, when light is incident at polarizing angle then reflected and refracted rays are mutually perpendicular, i.e., \[{{i}_{p}}+r={{90}^{o}}\]. Here, \[{{i}_{p}}\] is angle of reflection, and r is angle of refraction.You need to login to perform this action.
