A polarized light of intensity ${\mathrm{I}}_0$ is passed through another polarizer whose pass axis makes an angle of ${60}^{\mathrm{o}}$ with the pass axis of the former. What is the intensity of emerging polarized light from second polarizer?

• A

  $\mathrm{I}={\mathrm{I}}_0$
• B

  $\mathrm{I}=\frac{{\mathrm{I}}_0}{6}$
• C

  $\mathrm{I}=\frac{{\mathrm{I}}_0}{5}$
• Correct answer
  D

  $\frac{{\mathrm{I}}_0}{4}$

Hence, the correct answer is option: 'D'.
