What is difference between progressive wave and stationary wave |
| Answer» Differences Between Stationary and Progressive Waves\tIn the case of a stationary wave, the energy is not propagated onwards because each particle possesses its own characteristic vibration. But in a progressive wave, the reason for energy being transmitted from one point to another is the transfer of vibration within the molecules of the wave.\tThe\xa0particles\xa0of the stationary waves, that are present at the node are completely at rest while others rest for a very short time span. As against, all the particles of progressive waves are in continuous motion and thus do not rest permanently.\tSome specific\xa0velocity\xa0is associated with each particle and during motion, at the mean position, the particles attain their maximum velocity simultaneously in standing wave. While in the case of a progressive wave, all the wave particles move with the same maximum velocity at the mean position.\tIn a standing wave, the motion of the particles is non- transferrable but in a progressive wave, the motion is easily transferred to the particles in the forward direction.\tFor stationary waves, the\xa0energy\xa0is confined within the medium while progressive wave permits propagation of energy through the medium.\tStationary waves do not undergo forward motion and due to this its crests and troughs blink at the initial position. While this is not the case for progressive wave because the wave undergoes forward motion and thus the crests and troughs are also in motion.\tIn a stationary wave, the\xa0amplitude\xa0of each particle is 0 at the node and maximal at the antinode thus is different. However, in the progressive wave, the amplitude of each particle is the same but there is significant variation in phase. | |
