Electromagnetic Waves

1. the number of crests that pass a certain point in a given amount of time
3. transmits energy through matter and/or empty space
8. bees can see this type of radiation
9. the lowest part of a wave
11. water molecules absorb this type of radiation and increase the temperature of our food
12. the particles of the medium vibrate in a direction perpendicular to the direction that the wave moves
13. radio and TVs convert these waves into sound and picture
14. we sense this radiation as heat because it causes molecules to vibrate
15. extremely high frequency waves that are emitted during a nuclear explosion

2. describes the entire range of light that exists
4. the distance from the midpoint to the height of a crest (or bottom of a trough)
5. the only light that our eyes can see. we detect this light as color
6. blocked by bones and teeth
7. the highest part of a wave
10. the distance from one crest to the next
