Answer:
(a) The ratio of the pressure amplitude of the waves is 43.21
(b) The ratio of the intensities of the waves is 0.000535
Explanation:
Given;
density of gas, = 2.27 kg/m³
density of liquid, = 972 kg/m³
speed of sound in gas, = 376 m/s
speed of sound in liquid, = 1640 m/s
The of the sound wave is given by;
Where;
is the pressure amplitude
(b) when the pressure amplitudes are equal, the ratio of the intensities is given as;
