You have a series of simple polarisers that you can orient as you choose in succession along a beam. Can you arrange them so that if the beam were polarized to start with it would be unpolarized when it has passed through your succession of polarisers?
Homework Answers
No, it's not possible as simple polarisers have only one optical axis through which electric field vibrations can emerge out Which will remain only in one possible plane perpendicular to direction of propagation so we can't have unpolarised light.

vertically polarized laser. The laser has a power output of 1 mW
and the beam has a diameter of 2 mm. What is the intensity of the
laser beam before it travels through any polarizers?

Most natural light sources emit"unpolarized light, perhaps better described as "randomly polanzed" light. These light sources emit numerous brief bursts of light whose polarization directions are unrelated, so on average the resulting beam has all polarization angles equally represented. When unpolarized light with intensity In passes through a polarizer, its intensity I is cut in half, regardless of the orientation of the transmission axis of the polarizer: I= 10 Part D One way to produce a beam of polarized light with intensity...

Unpolarized light passes through two polarizing filters. After passing through the first filter the intensity of the light (11) is 17 W/m2. The first filter is vertical (0 degrees), while the second filter is angled at 34 degrees. What is the new intensity of the light? If you have unpolarized light passing through two polarizing filters that are lined up to the same direction. How can you rotate them to block all light from passing through? rotate one by 45°...
