2. the interval of time it takes for a motion to repeat
3. a measurement of the amount of energy transferred by a wave
5. repetitive movement back and forth through an equilibrium, or central, position, so that the maximum displacement on one side of this position is equal to the maximum displacement on the other side.
6. wave a wave vibrating in the direction of propagation.
8. a material that moves energy or light from one substance to another, or from one location to another, or from one surface to another
9. wave a vibration in matter that moves through a medium and transfers energy
11. interference when two waves overlap in such a way that they combine to create a larger wave
13. the interval of time it takes for a motion to repeat
14. the number of waves that pass a fixed point in a given amount of time
15. the periodic back and forth motion of a physical quantity, such as mechanical displacements or electric current, from a position of equilibrium
16. the point on a wave with the greatest positive value or upward displacement in a cycle

1. the lowest point below the rest position
4. wave movement
7. the distance between identical points, or adjacent crests, in the adjacent cycles of a waveform signal propagated in space or along a wire
10. interference occurs when waves come together so that they completely cancel each other out
12. wave a wave that moves perpendicularly to the direction of the wave's motion
