Question

State whether given statement is True or False
A wave is a disturbance that moves through a medium when the particles of the medium set neighboring particles into motion.

• A. True
• B. False

Answer 1

The correct option is A True

Sound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving. If a sound wave is moving from left to right through air, that is in an oscillatory motion, then particles of air will be displaced both rightward and leftward as the energy of the sound wave passes through it. The motion of the particles is parallel (and anti-parallel) to the direction of the energy transport. Here, the sound wave does not move the particles of the medium from one place to another but only the vibration or the disturbance moves.
Hence, the statement is true.
