Across
- 2. reflect off ionosphere
- 4. another type of electromagnetic wave produce by the sun
- 7. range of colors
- 8. wave interaction that occurs two or more waves to overlap
- 13. bending of waves around barriers and through openings
- 14. matter through which visible light is easily transmitted
- 15. matter that does not transmit any light
- 17. when lights or any wave bounces off an object
- 19. particle wave through
- 20. material that gives a substance it color by absorbing some color of light and reflecting others
- 24. the transfer of energy carried by light waves to particles of matter
- 25. carry large amounts of energy and can penetrate material very easily
- 26. bending of a wave as it passes at an angle from one medium to another
- 27. states that the angle of incidence is equal to the angle of reflection
Down
- 1. waves cover a wide range of waves in the EM spectrum
- 3. used in radar
- 5. the release of light energy by particles of matter that have absorbed energy
- 6. the entire range of EM waves
- 9. emission of energy in the form of EM waves
- 10. light can act as either particles or waves
- 11. emitted by the sun
- 12. very narrow range of wavelengths and frequencies
- 16. a tiny packet of light energy
- 18. pass through the ionosphere
- 21. matter transmits light but also scatter the light as it passes through matter
- 22. passing of light through matter
- 23. falling of a beam of light on a surface
