MCQ
In a standing wave, all particles of the medium cross the mean position with
- ADifferent speeds at different instants
- ✓Different speeds at same instant
- CSame speed at different instants
- DSame speed at same instant
✓
Answer
Correct option: B.
Different speeds at same instant
b
(b)
(b)
In a standing waves all particles of same wave have same $v$ and hence vibrate in phase passing the mean point at same time. The amplitude of the waves is different at different points hence the speed is different.
