What is differentiate between stationary & progressive wave
Answers
Answer :
stationery wave :
These waves remain stationary between two boundaries in the medium.
In these waves except nodes, all other particles of medium amplitude vibrate but all the amplitude of vibrations is different from one particle to another particle.
At any instant the phase of all particles between two nodes is same, but phase of particles on one side of node is opposite to the phase of other side of node.
These wave do not transmit energy in the medium.
Plane progressive wave :
1) these waves advanced in a medium with a definite velocity .
2)In this wave all the particles of the medium vibrate and the amplitude of vibration is the same for all of them.
3) At any instance the phase of vibration varies continuously from one particle to the other.
4) These waves transmit energy in the medium.
