Question:
Suppose that an unpolarized light beam is incident from the left on the arrangement of two polarizers. If the intensity of the light emerging on the right is 32% of the incident intensity, what must be the angle between the preferential directions of the polarizers? Answer in degrees
Polarization of light
The polarization of light is a process of transforming an unpolarized light to the polarized light. A polarised only has the electric field pointing in just one particular direction while the unpolarized light has the electric field pointin in all possible directions.
According to th law of Malus, the intensity of light emerging from the set of polarizers is equal to the product of the intensity of the incident light times square of the cosine of the angle of the polarizer. So the angle between the polarizers can be determined.
