Polarized by E&M Light is an electromagnetic wave, EM wave. The electric and magnetic fields both oscillate perpendicularly to the direction of propagation, making light a transversely polarized wave. As light travels through a medium, the oscillating electric field has an effect on electrically charged objects in the medium (mostly electrons). Oscillating charges create fluctuating electric (and magnetic) field vectors. Polarized light has a single direction for fluctuations of electric field vectors. Unpolarized light has no preferred direction for fluctuations...

1. Unpolarized light is incident upon a polarizer whose axis is tilted 30 degrees relative to vertical. What fraction of the light is transmitted through the polarizer? 2. In a two-slit interference pattern, the pattern becomes fainter as we move away from the central maximum due to Question 4 options: Interference Diffraction Resolution The Rayleigh criterion I don't know. 3. Huygens' principle states that Question 3 options: Monocromatic light incident upon two slits will form an interference pattern. Monocromatic light...
