Unpolarized light is passed through polarizer 1. The light then goes though polarizer 2 with its plane of polarization at 40.7° to that of polarizer 1. Polarizer 3 is placed after polarizer 2. Polarizer 3 has its plane of polarization at 54.8° to the plane of polarization of polarizer 2 and at 95.5° to that of polarizer 1. What fraction of the intensity of the original light gets though the last polarizer?

The fraction of the intensity of the original light that got through the last polarizer is![\frac{I_3}{I_o} = 0.0955](/tpl/images/0632/7506/62458.png)
Explanation:
From the question we are told that
The angle between polarizer 2 and polarizer 1 is![\theta_1 = 40.7^o](/tpl/images/0632/7506/e4745.png)
The angle between polarizer 3 and polarizer 2 is![\theta_ 2 = 54.8^o](/tpl/images/0632/7506/9cf71.png)
The angle between polarizer 3 and polarizer 1 is![\theta _3 = 95.5^o](/tpl/images/0632/7506/392b8.png)
The intensity of light emerging from the first polarizer can be obtained using the one half rule as follows
Here
is the intensity of light emerging from the polarizer 1
The intensity
of light emerging from the second polarizer is obtained using the cosine-squared rule the intensity of light incidenting on the second polarizer is already polarized by the polarizer 1
So the intensity is mathematically represented as
substituting for![I_1](/tpl/images/0632/7506/a446e.png)
Substituting values
The intensity
emerging from polarizer 3 is obtained using the cosine-squared rule as follows
substituting for![I_2 \ and \ \theta_2](/tpl/images/0632/7506/9a130.png)
