Write down two necessary conditions for the propagation of mechanical wave?
Answers
MEDIUM SHOULD BE ISOTROPIC: The properties of the medium should be the same in all directions.
ELASTICITY : The medium should have elasticity so that the particles return back to their original positions after being displaced.
INERTIA : This allows the particles to store kinetic energy.MINIMUM
FRICTION : So that the particles oscillate and the wave travels for a sufficiently long time and distance.these were the properties required for propagation of mechanical waves ,
