1.6 \times 10^5 \text{ 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(15\pi x - 6000\pi t)

. Here

y

and

x

are in metres and

t

is in second. The maximum pressure amplitude received to the observer's ear is

(24\pi) \text{ Pa}

, then find. (a) the density of the medium, (b) the displacement amplitude

A

of the waves received by the observer and (c) the power of the sound source.
