Lesson: Polarization of Electromagnetic RadiationPhysics
In this lesson, we will learn how to calculate the change in the intensity of light that is passed through a system of polarizing filters.
Sample Question Videos
If a polarizing filter reduces the intensity of polarized light to of its original value, what is the ratio of the amplitude of the electric and magnetic fields in the light incident from and emergent from the filter?
The angle between the axes of two polarizing filters is . By how much does the second filter reduce the intensity of the light coming through the first?
Two polarizing sheets are placed together to form a combination with the transmission axes of the polarizers oriented at an angle to each other. With the polarizers so aligned, the amount of light that passes through the sheets is of the maximum possible intensity of plane-polarized light that the combination can transmit. What percent of unpolarized light would be transmitted through the combination?
