Question

When unpolarized light beam is incident from air onto glass $(n=1.5)$ at the polarizing angle

• A. reflected beam is polarized 100 percent
• B. reflected and refracted beams are partially polarized
• C. the reason for (1) is that almost all the light is reflected.
• D. All of the above

Answer 1

Answer: (A)

If unpolarised light is incident at polarising angle, then reflected light is completely i.e., $100\%$ polarised.
