Question
When we throw a stone in a pond _________ is/are generated.
- A wave
- A periodic wave
- Ripples
- Both a and c
Hint:
Both A and C
The correct answer is: Both a and c
When stone is thrown into a pond or river, the water particles move up and down about their mean positions, while energy travels horizontally away from the impact point. This is a characteristic of transverse waves. These waves in the water due to the stone are also called ripples.
