What are stationary waves? Why are they called stationary waves? 

लघु उत्तरीय

उत्तर

  1. When two identical waves travelling along the same path in opposite directions interfere with each other, the resultant wave is called a stationary wave. 
  2. Stationary waves are called so because the resultant harmonic disturbance of the particles does not travel in any direction and there is no transport of energy.
