Question

In a standing wave, all particles of the medium cross the mean position with (A) Different speeds at different instants (B) Different speeds at same instant (C) Same speed at different instants (D) Same speed at same instant

Tardigrade Admin · Accepted Answer

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.

Q. In a standing wave, all particles of the medium cross the mean position with

Different speeds at different instants

Different speeds at same instant

Same speed at different instants

Same speed at same instant

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.
