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. $$\dfrac{I}{2}$$
2. $$\dfrac{I}{3}$$
3. $$\dfrac{3I}{4}$$
4. $$\dfrac{2I}{3}$$

Two polaroids $$P_1$$ and $$P_2$$ are placed with their axis perpendicular to each other. Unpolarised light of intensity $$I_0$$ is incident on $$P_1$$. A third polaroid $$P_3$$ is kept in between $$P_1$$ and $$P_2$$ such that its axis makes an angle $$45^\circ$$ with that of $$P_1$$. The intensity of transmitted light through $$P_2$$ is:
1. $$\frac{I_0}{4}$$
2. $$\frac{I_0}{8}$$
3. $$\frac{I_0}{16}$$
4. $$\frac{I_0}{2}$$
