Question: Consider sinusoidal sound waves propagating in these three different media: air at 0C, water, and iron. Use densities and speeds from Tables 14.1 and 17.1.

Consider sinusoidal sound waves propagating in these three different media: air at 0°C, water, and iron. Use densities and speeds from Tables 14.1 and 17.1. Each wave has the same intensity I0 and the same angular frequency wo.
(a) Compare the values of the wavelength in the three media.
(b) Compare the values of the displacement amplitude in the three media.
(c) Compare the values of the pressure amplitude in the three media.
(d) For values of wo = 2 000 π rad/s and I0 = 1.00 X 10─6 W/m2, evaluate the wavelength, displacement amplitude, and pressure amplitude in each of the three media.
