Question

Unpolarized light of intensity $I_0$ is incident on surface of a block of glass at Brewster's angle. In that case, which one of the following statements is true?

• A. transmitted light is partially polarized with intensity $\frac{I_0}{2}$
• B. transmitted light is completely polarized with intensity less than $\frac{I_0}{2}$
• C. reflected light is partially polarized with intensity $\frac{I_0}{2}$
• D. reflected light is completely polarized with intensity less than $\frac{I_0}{2}$

Answer 1

Answer: (D)

By polarizations due to reflection at a polarising angle reflected light is completely polarise and the intensity is less than average intensity $\frac{I_0}{2}$ .
