1. Parts of a Wave

2. crest Crest – the highest point of a wave.

3. trough Trough – the lowest point of a wave.

5. Wavelength – a measure from one point on one wave to the corresponding point on the next wave. Measured in meters.

7.  The distance a wave travels in a specific amount of time.  Meters per second Wave Speed

8. Equilibrium Equilibrium – rest position

9. Amplitude – the distance a wave rises or falls from the equilibrium. (How big the wave is) You need more energy to make the amplitude larger

10. http://www.pbslearningmedia.org/asset/lsps07_int_freq uency/ http://www.acoustics.salford.ac.uk/schools/lesson1/flash/ freq.swf Frequency – measurement of how many cycles can happen in a certain amount of time. Frequency is measured in hertz. Example: If a motor makes 50 revolutions in one second, we say it has a frequency of 50 hertz (Hz) per second.
