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 ?
- A reflected light is completely polarized witih intensity less than \(\frac{I_0}{2}\)
- B transmitted light is completely polarized with intensity less than \(\frac{I_0}{2}\)
- C transmitted light is partially polarized with intensity \(\frac{I_0}{2}\)
- D reflected light is partially polarized with intensity \(\frac{I_0}{2}\)
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.
