2 cards from this section. Quick, good the night before a test.
What is polarization in the context of light waves?
Think about how light behaves when it travels.
What does a polaroid do?
Consider what happens when light passes through it.
What happens to light that passes through a polaroid?
Think about what a polaroid is designed to do.
Malus's Law relates to which of the following?
Recollect the formula for intensity and its dependency on angle.
If you have unpolarized light with an intensity of 200 units passing through a single polarizer, what will be the transmitted intensity? If a second polarizer is then added at an angle of 45 degrees from the first, what will be the output intensity?
Remember to halve the intensity first and then apply the angle for the second polaroid.
Explain how to configure two polarizers to achieve maximum light transmission and provide a scenario where this could be useful.
Think about how you control light in different mediums.
