Physics

2. Hertz(Hz)
5. The material that carries a wave
6. A passing ambulance siren sounds higher pitched as it approaches and lower pitched as it moves away, due to compressed or stretched waves
7. EM Spectrum
9. EM radiation
12. When the crest of one wave perfectly meets the trough of another
13. The rate at which energy is transported, usually measured in meters per second (m/s)
14. Measure how much energy a wave carries
15. The bending or change in direction of light, sound, or water waves

1. Two waves meet in phase
3. The bending and spreading of waves as they pass through a narrow opening or around the sharp corner of an obstacle
4. The act of light or sound waves hitting a surface and bouncing back into the original medium
8. If you shake a rope up and down, you create this type of wave
10. It is how sound travels through air it is also known as a pressure wave
11. How far a wave travels in one cycle
