Waves

3. the distance between 2 crests or 2 troughs
5. the lowest point on a transverse wave
10. happens when a wave bounces after hitting a barrier.
12. a type of wave that needs a medium to travel through
13. the bending of waves around a barrier or through an opening
14. the highest point on a transverse wave
15. Occurs when light waves transfer energy to particles of matter.
16. the number of waves that pass by a point each second
19. waves in which the particles vibrate back and forth in compressional pulses

1. waves in which the particles vibrate in an up and down motion
2. wave height
4. of energy that travels as an electromagnetic wave. The source of this energy is usually the sun.
6. vibration produced in one object that is caused by the vibration produced in another
7. any disturbance that transfers energy through matter or space.
8. Occurs when light waves pass through an object without interacting.
9. when waves overlap
10. the change in direction of a wave when it changes speed as it travels from one material(medium) to another
11. an interaction of light with matter that causes light to change direction.
17. The matter a wave travels through
18. a type of wave that does NOT need a medium to travel through
