Waves

4. what we see when no colors or light enter our eye
5. a quick back-and-forth movement
7. the type of visible light we see when all colors enter our eye at the same time
9. the rate (how often) something that repeats over and over
10. a substance or material (solid, liquid, gas)
11. how loud a sound is, which depends on the amplitude of its sound wave
13. the type of wave in which the movement of the wave's medium is perpendicular (up and down) to the direction the wave is moving
14. describes when an object takes in or soaks up certain waves of light
16. the high point of a wave
17. a high frequency/energy form of electromagnetic radiation that can be used to see through human skin and take pictures of bones
19. another name for a compression wave
21. when a wave changes direction or speed as it enters a new medium
22. the height of the peak/crest of a wave above the resting line
24. the name for any type of wave that can only travel through a medium (solid, liquid, gas)
26. the type of wave in which a wave's medium is compressed (squeezed) in the same direction as the movement of the wave
28. the length of one wave, can be measured as the distance from the center of one peak (crest) to the center of the next peak (crest)
29. the low point of a wave
30. the name for a particle of light or packet of light

1. the of electromagnetic radiation with the highest energy and frequency, and shortest wavelength
2. the type of energy in movement/motion
3. a back and forth pattern of motion that transfers energy
6. when a wave bounces off an object
8. 2words a mathematical relationship where if one variable increases, the other decreases (example: frequency vs wavelength)
12. the name for any wave created by an earthquake
15. the type of light we can see
18. the type of light with a frequency just above what humans can see, but can cause sunburns and skin damage
20. the type of electromagnetic wave with the lowest energy and frequency, and the longest wavelength
23. the reflection of sound off a distant surface
25. the ability to do work
27. the highness or lowness of a sound, which depends on the frequency of its sound wave
