An overhead projector is turned on so its light shines on the screen at the front of the classroom_ The light from the projector is unpolarized, and the intensity of the light reaching the screen is 500 WIm?_
A single polarizer is then placed on the projector so the light passes through the polarizer before reaching the screen. The transmission axis of the polarizer is aligned at +40.00 angle (see the picture to see exactly what direction this is)_
(a) What is the intensity of the light reaching the screen now? 500 W/m?
(b) When the polarizer is rotated clockwise little, so the angle the transmission axis makes with our reference line is more than +40.08 _ the light reaching the screen does which of the following?
gets brighter; with no change in the angle at which it Is polarized
gets brighter; and it experiences change in the angle at which it is polarized
ets dimmer; with no change in the angle at which it is polarized
gets dimmer; and it experiences change in the angle at which it is polarized
stays the same intensity, with no change in the angle at which it Is polarized stays the same intensity, but it experiences a change in the angle at which it is polarized
