As we learnt in
Intensity of the wave -
mass density
angular frequency
Amplitude
Wave speed
- wherein
flow of energy per unit area of cross section of the string in the unit time is known as intensity of wave.

As sound wave travel through air, the element of air vibrate to produce change in density and pressure along the direction of motion of the wave.
- wherein
sound wave travel through any material medium with a speed that depend on the properties of medium.
