For a sound wave travelling towards `+x` direction, sinusoidal longitudinal displacement `epsi` at a certain time is given as a function of `x` (Fig). If bulk modulus of air is `B=5xx10^5(N)/(m^2)`, the variation of pressure excess will be

The pressure required to reduce the given volume of water by 1% is, (Bulk modulus of water =2xx10^(9)N//m^(2) )

The equation of displacement due to a sound wave is s = [s_0sin^2(omegat-kx)] if the bulk modulus of the medium is B , then the equation of pressure variation due to that sound is

A sound wave of wavelength 20pi cm travels in air if the difference between the maximum and minimum pressures at a given point is 3.0xx10^-3 N//m^2 . Now sound level is increased by 20 dB, if the new amplitude of vibration of the particles of the medium at that given point is 20k (in Å ) then 'k' is : (The bulk modulus of air is 1.5xx10^5 N//m^2 ) (wavelength is same in both cases )
