Well I know that cos of 90 degrees=0 which means no light will go through the crystal and if cos of 0 degrees=1 i.e the crystal cross section will match thus max polarised light will pass through
Homework Statement
An angle is given between 2 polarizer's (45 degrees), through them light passes (unpolarized than after passing through the first one it polarizes), some of the light its shown on the display. For how much does the angle needs to be increased for the intensity of light to be...
