Question

If the light is polarised by reflection, then the angle between reflected and refracted light is

• A. 180\(^\circ\)
• B. 90\(^\circ\)
• C. 45\(^\circ\)
• D. 36\(^\circ\)

Hint:

When light is polarized by reflection, the angle between the reflected and refracted rays is 90°.

Answer 1

The Correct Option is B

Step 1: Use Brewster's Law.
According to Brewster's law, the angle of polarization occurs when the reflected and refracted light are perpendicular to each other. This corresponds to an angle of 90° between the reflected and refracted beams.
Step 2: Conclusion.
Thus, the angle between reflected and refracted light is 90°.
Final Answer: \[ \boxed{90^\circ} \]
