CBSE Class 12-science Answered
A ray of light reflected from surface of glass at an angle of 56*40' is found to be completely plane polarised. What is the angle of refraction of the transmitted ray? (* stands for degree)

Expert Answer
It is the case of brewester"s law , here the angle between refracted and reflected ray is 900.Here angle of incidence is known as brewster angle iB.
iB=56* 40'
?=Tan iB------(1)
We know siniB/sin r=?----(2)
use (1) and (2) and find angle r.
