JEE MainPhysicsWave OpticsMCQ+4 / −1
An unpolarised light beam of intensity 2I02 I_{0}2I0​ is passed through a polaroid P and then through another polaroid Q which is oriented in such a way that its passing axis makes an angle of 30∘30^{\circ}30∘ relative to that of P. The intensity of the emergent light is
  1. A
    I04\frac{\mathrm{I}_{0}}{4}4I0​​
  2. B
    I02\frac{\mathrm{I}_{0}}{2}2I0​​
  3. C
    3I04\frac{3 I_{0}}{4}43I0​​
