Two Polaroids \(P_1\) and \(P_2\) are placed with their axis perpendicular to each other. Unpolarised light \(I_0\) 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. \(\frac{I_0}{2}\)
