Question: A beam of polarized light passes through a polarizing filter. When the angle between the polarizing axis of the filter and the direction of polarization

A beam of polarized light passes through a polarizing filter. When the angle between the polarizing axis of the filter and the direction of polarization of the light is θ, the intensity of the emerging beam is l. If you now want the intensity to be I/2, what should be the angle (in terms of θ) between the polarizing angle of the filter and the original direction of polarization of the light?
