Question
When waves move on the surface of the water, the water molecules execute:
- Linear motion
- Oscillatory motion
- Circular motion
- None of these
Hint:
Overall round motion.
The correct answer is: Circular motion
- When waves move on the surface of the water, the water molecules execute - circular motion.
- In a surface wave, particles of the medium move up and down as well as back and forth in an overall circular motion.
- So, the correct option is c.
