Unpolarized light of intensity \(I_0\) incident on surface of a block of glass at Brewster's angle. In that case, which one of ihe following statements is true ?
Pick an option to check your answer.
Answer & Solution
Correct Answer
(A) reflected light is completely polarized witih intensity less than \(\frac{I_0}{2}\)
Step-by-step Solution
Detailed explanation
When unpolarised light is incident at Brewster 's angle then reflected light is completely polarized and the intensity of the reflected light is less than half of the incident light.
