4 cards from this section. Quick, good the night before a test.
What is Huygens' principle?
Think about how waves propagate from one point to another.
What is the result when two coherent light sources meet?
Recall the concept of constructive and destructive interference.
What does Huygens' principle allow us to predict?
Consider the information shared by each point on a wavefront.
True or False: Polarized light oscillates in multiple planes.
Think about how polarized sunglasses work.
Consider a double-slit experiment where the slits are 0.5 mm apart and the distance to the screen is 2 m. If the wavelength of light is 600 nm, find the distance between the first and second bright fringes.
Set m=1 for the first fringe and m=2 for the second fringe.
Explain why polarized sunglasses reduce glare. What physics principles support this?
Consider the orientation of light waves in relation to how they reflect off surfaces.
