Waves

3. The distance from one crest to another, or from one through to another, of a wave.
4. Motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance.
6. The Rance of all types of EM radiation.
8. When light bounces off an object.
9. Waves where the displacement of the medium is in the same direction as the direction of the travelling wave.
11. An electric and magnetic disturbance traveling through space at the speed of light.
13. A material that moves energy or light from one substance to another, or from one location to another, or from one surface to another.
14. Number of waves that pass fixed point in unit time.
15. When two waves overlap in sushi a way that they combine to create a larger wave.

1. The maximum displacement of points on a wave.
2. The distance the wave travels in a given amount of time.
5. The bending of a ray when it passes at an angle from one medium into another in which its speed is different.
7. Occures when waves come together so that they completely cancel each other out.
10. The increase (or decrease) in the frequency of sound, light, or other waves as the source observer move towards (or a way from) each other.
12. The spreading out of waves as they pass through an aperture or around objects.Constructive interference
