Longitudinal wave consists of:
Correct answer: B. Compression and rarefactions
- A. Crests and troughs
- B. Compression and rarefactions
- C. Crests and compressions
- D. Troughs and rarefactions
Explanation
A longitudinal wave consists of compressions and rarefactions. Compressions are regions of high pressure and density, while rarefactions are regions of low pressure and density.

About Progressive Waves
Progressive waves transfer energy through a medium or space while particles oscillate about their equilibrium positions. The work includes amplitude, wavelength, frequency, period, phase difference, wave speed and the progressive wave equation, while distinguishing travelling waves from stationary waves, where the pattern has fixed nodes and antinodes.
