A polarized light wave passes through a polarizing filter which reduced the intensity of the light to 25% of the incident intensity. What would the intensity become if the incident light is unpolarized?

PLEASE EXPLAIN :))

Here,when the polarized light incident on a polarizer filter,its intensity of the emerging plane polarized light will reduce as per the Malu's law,and be calculated.But if the incident light on polarizer filter is unpolarized light,it will reduce its intensity to half for the emerging polarized light irrespective of the passage angle of the polarizer filter.

Polarized light passes through a polarizing filter which has an axis of transmission oriented at θ1 = 39.4 degrees from vertical. The intensity of the emerging light is measured to be I1 = 700 W/m2. The polarizer is then rotated so that its axis of transmission is θ2 = 70.9 degrees from vertical, and the emerging light is now measured to be 290 W/m .

A beam of light is a mixture of unpolarized light with intensity Ia and linearly polarized light with intensity Ib. The polarization direction for the polarized light is vertical. When this mixed beam of light is passed through a polarizer that is vertical, the transmitted intensity is 16.8 W/m2; when the polarizer is at an angle of 55.0° with the vertical, the transmitted intensity is 8.68 W/m2.
