In each of the following cases, initially vertically polarized light enters the polarizing apparatus with the same initial intensity. Which polarizing apparatuses will cause the light to exit with the largest intensity, 90° from its initial polarization?
a) A single polarizing filter, oriented 90° from the vertical
b) Two polarizing filters, the first 45° from the vertical and the second 90° from the vertical
c) Two polarizing filters, the first 60° from the vertical and the second 90° from the vertical
d) Two polarizing filters, the first 30° from the vertical and the second 90° from the vertical.

- Multiple ChoiceUnpolarized light strikes a polarizing filter. It then passes through a second polarizer. The axis of the second polarizer is tilted from the axis of the first. If the intensity of light emerging from the second polarizer is. what intensity does the light have as it strikes the first polarizer?1154views

Unpolarized light with intensity of 6 W/m2is incident on a polarizer.If the polarizer's transmission axis is at an angle of 45° above the horizontal, draw a diagram of this system and find the intensity of transmitted light.
