Unpolarized light with an intensity of $I_0=16\frac{W}{m^2}$ is incident on a pair of polarizers. The first polarizer has its transmission axis aligned at ${50}^{\circ }$ from the vertical. The second polarizer has its transmission axis aligned at ${20}^{\circ }$ from the vertical.

What is the intensity of the light when it emerges from the first polarizer?

Q. Unpolarized light with an intensity of $I_0=16\frac{W}{m^2}$ is incident on a pair of polarizers. The first polarizer has its transmission axis aligned at ${50}^{\circ }$ from the vertical. The second polarizer has its transmission axis aligned at ${20}^{\circ }$ from the vertical.

Q. Unpolarized light of intensity $I_0$ is incident on a polarizer and the emerging light strikes a second polarizing filter with its axis at 45${}^{\circ }$ to that of the first. The intensity of the emerging beam :

Q. Unpolarized light of intensity $32\frac{W}{m^2}$ passes through three polarizers such that the transmission axis of the last polarizer is crossed with that of the first. The intensity of final emerging light is $3\frac{W}{m^2}$ . The angle between the first two transmission axes of the polarizers is:

Q. Unpolarized light of intensity $32{\text{W/m}}^2$ passes through three polarizers such that the transmission axis of the last polarizer is crossed with the first. If the intensity of emerging light is $3{\text{W/m}}^2$, the angle $\theta$ between the transmission axes of the first two polarizers and the angle $\varphi$ at which transmitted intensity will be maximum are

Q. Unpolarized light of intensity $32{\text{Wm}}^{-2}$ passes through three polarizers such that transmission axes of the first and second polarizer makes an angle ${30}^{\circ }$ with each other and the transmission axis of the last polarizer makes an angle $\theta$ with the axis of second polarizer as shown in figure. The intensity of final emerging light will be-
