NEET · Physics · STD 12 - 10. Wave optics
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 \(45^o \) with that of \(P_1\) .The intensity of transmitted light through \(P_2\) is
- A \(\frac{{I_0}}{4}\)
- B \(\frac{{I_0}}{8}\)
- C \(\frac{{I_0}}{{16}}\)
- D \(\frac{{I_0}}{2}\)
