You simultaneously shine two light beams, each of intensity I0, on an ideal polarizer. One beam is unpolarized, and the other beam is polarized at an angle of exactly 30.0∘ to the polarizing axis of the polarizer. Find the intensity of the light that emerges from the polarizer. Express your answer in term of I0 .

The emerging intensity is equal to 0.75

Explanation:

The initial intensity of the light =

The angle of polarization β = 30°

We know that the polarized light intensity is related to the initial light intensity by

=

where is the emerging polarized light intensity

inserting values gives

= 30°

30° = = = 0.75

= 0.75

could i give you a exaplo that could you?
