Question

With the propagation of longitudinal waves through a medium, the quantity transmitted is

• A. matter
• B. energy
• C. energy and matter
• D. energy, matter, and momentum

Answer 1

The correct option is B

energy

Explanation of correct answer: option (b) energy

Longitudinal Waves: Longitudinal waves are those in which the medium's displacement and the wave's propagation direction are both in the same direction.

1. In a longitudinal wave, compression is the phase where the atoms are closest together.
2. A period in a longitudinal wave where the ions are farthest apart is known as rarefaction.
3. The wavelength is the distance between two successive compressions and rarefaction.

There is no physical movement of any part of the medium during the transmission of longitudinal waves, therefore only energy is transported to the medium's particles, turn by turn in the wave's propagation direction due, to the interatomic forces acting on the atom.

Hence, the correct answer is (b)energy.
