Question

In a medium, a mechanical wave travels. With the wave, which of the following quantities is moved from one point to another?

  1. Mass
  2. Speed
  3. Density
  4. Energy

hintHint:

The ability to do work.

The correct answer is: Energy


    • Waves transfer energy but not mass.
    • Energy moves from one point to another, but not particles(they vibrate).
    • Energy is transferred in waves through the vibration of particles.
    • So, the correct option is d.
