Across
- 2. The mnemonic for remembering colors of visible light from longest wavelength to shortest wavelength
- 3. Electromagnetic waves with frequencies just below those of visible light. They are not seen by us but are felt as heat.
- 6. A transparent object that separates white light into the colors that make it up
- 7. The longest wavelength and lowest energy electromagnetic waves
- 10. The bouncing back of waves when they strike the surface of a new medium
- 11. The shortest wavelength and highest energy electromagnetic waves
- 12. Electromagnetic waves with frequencies just above those of visible violet light. They cause sunburn.
- 14. The passing of waves through a medium
- 15. Matter that transmits most of the light that strikes it like glass
- 16. ___________ reflect light.
- 17. When light travels from air through a solid like glass it _________ ________.
Down
- 1. The electromagnetic waves that can be detected by the human eye
- 4. The bending of waves caused by a change in their speed as they pass from one medium to another
- 5. A device that separates white light into colors by passing it through many slits
- 8. The taking in of a wave's energy
- 9. Matter that does not transmit light like the top of the table
- 13. The range of all frequencies of electromagnetic waves
- 14. Matter that transmits light waves but scatters them as they pass through
