A) (i) only
B) (ii)only
C) (i) and (iii)
D) All statements are correct
Correct Answer: C
Solution :
According to the Brewster?s 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, \[{{i}_{p}}=\]angle of reflection \[r=\]angle of refraction Note: The polarising angle for air-glass is\[{{57}^{o}}\].You need to login to perform this action.
