A plane polarized light is incident on a polariser with its pass axis making angle \theta with x -axis, as shown in the figure. At four different values of \theta, \theta=8^{\circ}, 38^{\circ}, 188^{\circ} and 218^{\circ}, the observed intensities are same. What is the angle between the direction of polarization and x -axis ?
