One sound wave travels in air and the other in water, their intensities and frequencies being equal. Calculate the ratio of their (a) wavelength, (b) pres- sure amplitudes and (c) amplitudes of vibration of particles in air and water. Assume that the density of air is 1.293 kg/m3 , and sound velocity in air and water is 331 and 1450 m/s, respectively. |
