(a) A longitudinal wave propagating in a water-filled pipe has intensity `3.00xx10^(-6) W//m ^(2)` and frequency `3400 H_(Z)` . Find the amplitude `A` and wavelength `lambda` of the wave . Water has density `1000 kg//m ^(3)` and bulk modulus `2.18xx10^(9) Pa`. (b) If the pipe is filled with air at pressure `1.00 xx10^(5)` Pa and density `1.20 kg//m^(3)`, What will be the amplitude `A` and wavelength `lambda` of a longitudinal wave the same intensity and frequency as in part (a) ?  (c ) In which fluid is the amplitude larger, water or air? What is the ratio of the two amplitude ? Why is this ratio so different from/ Conider air as diatomic.
