MCQ
A light has amplitude $A$ and angle between analyser and polariser is $60^{\circ}$. Light is reflected by analyser has amplitude
  • A
    $A \sqrt{2}$
  • B
    $A / \sqrt{2}$
  • C
    $\sqrt{3} A / 2$
  • $A / 2$

Answer

Correct option: D.
$A / 2$
The amplitude will be $A \cos 60^{\circ}=A / 2$
