Question
In a medium, a mechanical wave travels. With the wave, which of the following quantities is moved from one point to another?
- Mass
- Speed
- Density
- Energy
Hint:
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.
