After passing through a polarizer, a linearly polarized light of intensity \(I\) is incident on an analyser making an angle of \(30^\circ\) with the axes of the polariser. The intensity of light emitted from the analyser will be:
| 1. | \(\frac{I}{2}\) | 2. | \(\frac{I}{3}\) |
| 3. | \(\frac{3I}{4}\) | 4. | \(\frac{2I}{3}\) |
