Question

Which features do sound waves have that ocean and light waves do not? Check all that apply.

compressions
rarefactions
amplitude
wavelength
crests
frequency
speed

Answer 1

- Compressions (check)
- Rarefactions (check)

Explanation: Sound waves are longitudinal mechanical waves that travel by alternating compressions and rarefactions of the medium. Amplitude, wavelength, frequency and speed are properties of all types of waves; crests are a feature of transverse/surface waves (like ocean and electromagnetic waves) and do not apply to longitudinal sound waves.
