Across
- 6. to bounce off without absorbing
- 8. the wave that has the lowest frequency
- 9. a type of wave that carries energy from one place to another even through empty space
- 12. anything that takes up space and has mass (solid, liquid, gas, plasma)
- 13. red, orange, yellow, green, blue, indigo, violet light
- 14. a range of different forms of light from radio to gamma rays (wavelengths large to small).
- 15. the ability to make things move or change
- 16. how often or fast something happens
- 18. the wave with the highest frequency
- 20. a type of invisible light that is beyond violet on the spectrum
Down
- 1. the maximum height of a wave (intensity: brightness or loudness)
- 2. the distance from one peak of a wave to the next
- 3. source an object that emits light
- 4. a pattern that describes how energy is carried from one place to another
- 5. a group of atoms joined together in a particular way
- 7. to pass through (no change occurs)
- 10. a curved line that shows the characteristics of a wave (shows wavelength and amplitude)
- 11. the number of peaks in a wave that pass in a second
- 17. to give off
- 19. to form a mental picture of something that cannot be seen
- 21. to take in (results in a change)
