Vocab words(waves)

3. when the electric current has multiple paths to flow through.
7. a wave that is an oscillation of matter, and therefore transfers energy through a medium.
9. the substance that transfers the energy, or light from one substance to another substance or from one place to another, or from one surface to another.
10. A node is a point along a standing wave where the wave has minimum amplitude.
12. a point on a surface wave where the displacement of the medium is at a maximum
15. when all external forces (including moments) acting on it are balanced.
16. motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance.
17. a periodic disturbance of the particles of a substance which may be propagated without net movement of the particles, such as in the passage of undulating motion, heat, or sound.
18. Perpendicular lines are those lines that intersect each other at 90 degrees.

1. movement of a wave
2. the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.
4. a wave vibrating in the direction of propagation.
5. he property of matter and radiation which is manifest as a capacity to perform work (such as causing motion or the interaction of molecules).
6. regular variation in magnitude or position around a central point.
8. the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.
11. A trough is the opposite of a crest, so the minimum or lowest point in a cycle.
13. the number of waves that pass a fixed point in unit time.
14. the time it takes for two successive peaks, or one wavelength, to pass through a fixed point.
