assume that the bulk madulus and density of seavater are B= 2.34 x 10^9 N/m^2 and p = kg/m^3. From a point source inside the ocean we generate a sound wave. This wave propagates isotropically (the same in all direction, spherical wave) with frequency of f= Hz. The amplitude of the wave at m from the source of the sound is Sm=m.
a What is the speed of propagation of the sound wave?
b What is the intensity of the sound wave at 10m from the source of sound
c Suppose we now replace this medium (seawater) with air, we keep the same amplitude of the wave at m and the same frequency. What is the intensity of sound wave at m from the source of sound?
