The Intensity of the Emerging Light can be calculated using Malus Law.

and It comes out to be
I' = I/2

The intensity of the polarised light which is emerging is \frac{i}{2}.

Explanation:

We are given a certain amount of light incident on a polaroid whose intensity is considered as i.

Where 'i' is the nature of the light that is incident.

  • It is basically unpolarized that is it contains both the positive and negative poles of light that is i^+ and i^- are present in the incident light respectively.
  • We are passing the light through a polaroid, hence we can be sure that only one pole shall emerge out.
  • Hence, the intensity of the light that will come out will have an intensity \frac{i}{2}.

To know more:

When an unpolarised light of intensity i is passed through a polaroid what us the intensity of the linearly polarizied light ? Does it depend on the orientation of the polaroid ?
