Across
- 2. the release of light energy by particles if matter that have absorbed energy
- 6. the emission of energy in the form of EM waves
- 7. the transfer of energy carried by light waves to particles of matter
- 8. is the bending of waves around barriers or through openings
- 9. the entire range of EM waves
- 10. frequency modulation
- 11. is a wave interaction that occurs when two or more waves overlap
- 14. occurs when light or any other wave bounces off an object
- 15. matter through which visible light is easily transmitted
- 18. a wave that that can travel through space or matter and consists of changing electric magnetic fields
- 20. a material that gives a substance its color by absorbing some colors of light and reflecting others
- 21. matter that does not transmit any light
- 22. matter transmits light but also scatters the light as it passes through the matter
Down
- 1. a tiny packet of light energy
- 3. is the bending of waves as it passes at an angle from one medium to another
- 4. states that the angle of incidence is equal to the angle of reflection
- 5. cover a wide range of waves in the EM spectrum
- 12. the idea that light can act as either particles or waves
- 13. is the passing of light through matter
- 16. amplitude modulation
- 17. are absorbed by your skin when they strike you body
- 19. the very narrow range of wavelengths and frequencies in the electromagnetic spectrum
