For sound waves in air with frequency 1000 Hz, a displacement amplitude of 1.2*10^-8 m produces a pressure amplitude of 3.0*10^-2 Pa. Use vsound= 344 m/s.

a) For 1000-Hz waves in air, what displacement amplitude would be needed for the pressure amplitude to be at the pain threshold, which is 30 Pa?

b) For what wavelength will waves with a displacement amplitude of 1.2*10^-8 m produce a pressure amplitude of 1.5*10^-3 Pa?

c) For what frequency will waves with a displacement amplitude of 1.2*10^-8 m produce a pressure amplitude of 1.5*10^-3 Pa
