When the propagation of a longitudinal wave through a material medium takes place, the quantities transmitted in the direction of propagation are:
Correct answer: D. Energy and momentum
- A. Energy, momentum, and mass
- B. Energy
- C. Energy and mass
- D. Energy and momentum
Explanation
When a longitudinal wave propagates through a material medium, the quantities transmitted in the direction of propagation are energy and momentum. Longitudinal waves transmit energy through the oscillations of particles in the medium, and they also carry momentum.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
