Question

With the propagation of a longitudinal wave through a material medium, the quantities transmitted in the direction of propagation are:

• A. Energy , momentum and mass
• B. Energy
• C. Energy and mass
• D. Energy and linear momentum

Answer 1

The correct option is D Energy and linear momentum

The vibrating particles, transmits the disturbance(wave pulse) by inducing the vibration in neighbour particle. In this manner the wave propagates in the medium.
$\Rightarrow$During the process of tranmission of a wave pulse, the transfer of energy and linear momentum takes place without the actual transfer of mass.
In case of longitudinal waves, the transfer of linear momentum and energy takes place along the direction of propagation.
