Question

Which of the following statements accurately describes a key characteristic of longitudinal waves?
Options
A The particles of the medium vibrate perpendicular to the direction of wave propagation.
B They can only propagate in a vacuum.
C They propagate via compressions and rarefactions, with particles vibrating along the direction of wave propagation.
Correct Answer
D Examples include electromagnetic waves and waves on a string.
Correct Answer

Option C is the correct answer.

Detailed Explanation

The document states: 'Longitudinal wave is such that the particles causing the wave vibrate along the direction of propagation of the wave.' and 'A longitudinal wave propagates via compression and rarefaction.' Option A describes transverse waves. Option B is incorrect; longitudinal waves require a medium. Option D describes transverse waves.

Hint

Focus on the definition and examples provided for longitudinal waves in the initial sections of the document.
