A wave is a disturbance that ____________________ energy through matter or space.
2. Define medium.
A medium is a substance or __________________ which carries the wave. (Example: air or water)
3. Know the difference between transverse and longitudinal waves.
a. Transverse waves: are waves in which particles vibrate with an ________________________________
motion. They have crests and troughs.
i. Crest: ________________ point of a wave
ii. Trough: ________________ point of a wave
b. Longitudinal waves: are waves which vibrate ________________________________ or parallel to
wave travel. They have areas of compression and rarefaction.
i. Compression: particles of a wave are _______________ together.
ii. Rarefaction: particles of a wave are __________________________.
