Mini Glossary

- amplitude: Measure of the energy that a wave carries.
- crest: The high point of the transverse wave.
- frequency: The number of wavelengths that pass a fixed point in one second.
- period: The amount of time it takes one wavelength to pass a fixed point.
- rarefaction: The section in a compression wave where the material is less crowded and more spread out.
- trough: The low point of the transverse wave.
- wavelength: The distance between one point on a wave and the nearest point just like it.

1. Review the key terms and their definitions in the Mini Glossary above. Explain how a transverse wave's wavelength is different from its amplitude.
