Question

What is the transmitted intensity of light if unpolarized light passes through a single polarizing filter and the initial intensity is 80 W/m2

Answer 1

Answer:

The transmitted intensity is   $I = 40 \ W/m^2$

Explanation:

From the question we are told that

     The intensity of the unpolarized  light  $I_o = 80 \ W /m^2$

Generally for a single filter the transmitted intensity of light  is mathematically evaluated as

           $I = \frac{I_o}{2}$

substituting values

          $I = \frac{80}{2}$

          $I = 40 \ W/m^2$
