Question

Briefly explain the difference between traveling waves and standing waves.

Answer 1

S.No.	Progressive waves	Stationary waves
1.	Crests and troughs are formed in transverse progressive waves, and compression and rarefaction are formed in longitudinal progressive waves. These waves move forward or backward in a medium i.e., they will advance in a medium with a definite velocity.	Crests and troughs are formed in transverse stationary waves, and compression and rarefaction are formed in longitudinal stationary waves. These waves neither move forward nor backward in a medium i.e., they will not advance in a medium.
2.	All the particles in the medium vibrate such that the amplitude of the vibration for all particles is same. particles. The amplitude is minimum or zero at nodes and maximum at antinodes.	Except at nodes, all other particles of the medium vibrate such that amplitude of vibration is different for different.
3.	These wave carry energy while propagating.	These waves do not transport energy.
