Question

Which one of the following statements is CORRECT about wave?
1. In a wave, energy is transferred but not matter.
2. In a wave, neither matter nor energy is transferred.
3. In a wave, matter is transferred but not energy.
4. In a wave, both matter and energy are transferred.

Answer 1

Correct Answer - Option 1 : In a wave, energy is transferred but not matter.

CONCEPT:

• Wave motion: The type of disturbance that travels through a medium due to repeated vibrations of the particles of the medium about their mean positions is called wave motion.

There are two types of wave motion:

• Longitudinal wave motion: It is that wave motion in which individual particles of the medium execute simple harmonic motion about their mean position along the same direction, in which the wave is propagated.
  • For example: Sound waves
• Transverse wave motion: Vibration of particles in a medium and the propagation of waves are perpendicular to each other.
  • Example: Waves on the surface of the water, waves in a string.

EXPLANATION:

• A wave is a disturbance that propagates and transports energy and momentum without the propagation of matter. Hence, option 1 is correct.
