Using the method of dimension, derive an expression for the velocity of sound waves. assume that the velocitu depends on:
(i) modulus of the elasticity e of the medium
(ii) the density of the medium p take constant k=i

50.)the diagram below represents the wave fronts produced by a point source moving to the right in a uniformmedium. observers are located at points a and b.compared to the wave frequency and wavelength observed at point a, the wave observed at point b has a(1) higher frequency and a shorter wavelength(2) higher frequency and a longer wavelength(3) lower frequency and a shorter wavelength(4) lower frequency and a longer wavelength
