For sound waves in air with frequency 1000 Hz, a displacement amplitude of 1.2×10−8m produces a pressure amplitude of 3.0×10−2Pa. Water at 20∘C has a bulk modulus of 2.2×109Pa, and the speed of sound in water at this temperature is 1480m/s. a)For 1000-Hz sound waves in 20∘C water, what displacement amplitude is produced if the pressure amplitude is 3.0×10−2Pa?
