When a longitudinal wave moves through a certain medium, the quantity which is transmitted through the medium is
general-sciencephysics-mechanics
- Amaterial of the medium only
- Benergy only
- Cboth material of the medium and energy
- Dnone of the above
Explanation
A wave transmits energy (and momentum) through a medium; the particles of the medium merely oscillate about their mean positions and are not carried along with it. In a longitudinal wave the oscillation is parallel to the direction of propagation, but there is still no net transport of material. Hence energy only - B.
