Waves

2. How fast waves are actually traveling through space.
5. Oscillating electric and magnetic fields that move together at the speed of light.
6. A wave that moves by squishing and stretching the medium in the same direction it travels.
8. The "physical size" of one single wave.
10. The way waves bend around corners or spread out after passing through a narrow opening.
12. Happens when two or more waves meet up while traveling through the same medium, and their displacements are in the same direction.
14. The "stuff" or substance that a wave or force travels through.
15. The change in frequency of a wave caused by the relative motion between the source of the wave and the observer.

1. A "clash" between two waves where they end up canceling each other out.
3. The "size" or "strength" of a wave.
4. A wave in which the particles of the medium vibrate at right angles to the direction of energy transfer.
7. The "bending" of light as it passes from one transparent material into another.
9. A ripple of energy traveling through space.
11. The number of waves that pass a fixed point in a given unit of time.
13. What happens when a wave hits a surface that it cannot pass through and bounces back into the medium it came from.
