5 quick questions — pick an answer to see if you’re right.
1. Which set lists four behaviors that show light is a wave?
2. Young's double-slit experiment is evidence of which wave behavior?
3. A thin film of oil on a wet road shows swirling rainbow colors. What causes this?
4. Polarization is the filtering out of one orientation of light. What does it show about light?
5. Using "blue to, red away," how does light from a star moving toward Earth appear?
