A light ray is incident on a glass slab it is partially reflected and partially transmitted. Then the reflected ray is
- A. completely polarised and highly intense.
- B. partially polarised and poorly intense
- C. partially polarised and highly intense
- D. completely polarised and poorly intense.
Step-by-step solution
When unpolarized light is incident on a glass slab, the reflected light is generally partially polarized except at Brewster's angle where it is completely polarized. Since the question does not specify Brewster's angle, the reflected ray is partially polarized. The intensity of reflected light is typically low (poorly intense) compared to the transmitted light. Hence, option B is correct.
