A point sound source is situated in a medium of bulk modulus `1.6 xx 10^5 N//m^2`. An observer standing at a distance 10 m from the source writes down the equation for the wave as `y = A sin (15pi x - 6000 pi t)`. Here y and x are in metres and t is in second. The maximum pressure amplitude tolerable by the observer's ear is `24 pi Pa`. Find : the density of the medium.

Explanation

`1 kg//m^3`
