Which of the following statements are true for a stationary wave?

âIn a stationary wave any particle at its given position has fixed amplitude of.

âThe oscillations time period of all the particles are same. So, they all cross their mean position at the same time.


âThere no transfer of heat between nodes because nodes are the points which are always at rest position.
