An incoherent mixture of linearly polarized light and circularly polarized light is viewed through a Polaroid. The position of the polaroid corresponding to the maximum intensity of transmitted light is found. When the polaroid is rotated from this position through an angle a = 30°, the light intensity decreases by p = 20%. Find the ratio of the intensity Ik of circularly polarized light to the intensity of linearly polarized light Il.
