Question

When waves travel through water, why do the moving water particles continue to return to their starting position?

Answer 1

Answer:

The correct answer is option c.

Explanation:

Conduction of a disturbance from one point to another is termed as a wave. A wave signifies the conduction of energy from one point to another via a material medium. However, a wave may or may not need any form of material medium for conduction. When a wave requires a material medium it is termed as a mechanical wave, while when the wave does not need a material medium for conduction it is termed as electromagnetic waves.  

In the case of mechanical waves, the energy is conducted via the vibration of particles of the medium via which the wave passes. In the case of electromagnetic waves, energy is conducted via the vibration of magnetic or electric fields. Waves perform the role of transmitting energy from one point to another, however, in the process, no movement of matter takes place.  

Answer 2

Answer:

B. Waves transfer both matter and energy.

Explanation:

When waves travel through water, the moving water particles continue to return to their starting position because waves transfer both matter and energy.
