Across
- 5. a wave that can travel through space or matter and consists of changing electric and magnetic fields
- 7. matter that doesn’t transmit any light
- 8. when a light or any other wave bounces off an object
- 9. the lowest wavelength and frequency of all em waves
- 10. frequency modulation
- 12. a very narrow range of wavelengths an frequencys
- 15. the bending of waves around barriers or the opening
- 16. the falling of a beam of light on a surface
- 18. amplitude modulation
- 19. a tiny packet of energy
- 20. the whole range of EM waves
- 21. the passing of light throughout matter
- 23. matter which is visible light that is easily transmitted
- 24. carry large amounts of energy and can penetrate materials very easily
- 25. the transfer of energy carried by light waves to particles of matter
Down
- 1. have shorter Wavelength and higher frequency than radio waves
- 2. the release of light energy by particles of matter that have absorbed energy
- 3. are prouduced by the sun
- 4. a wave interaction that occurs when 2 or more waves overlap
- 6. an angle of incidence is equal to the angle of reflection
- 11. the range of colors
- 13. the idea that light can act as either particles or waves
- 14. the emission of energy through the form of em waves
- 17. an electromagnetic wave produce by the sun that has shorter wavelength and higher frequency than visible light
- 22. the bending of a wave as it passes at an angle from one medium to another
