Q. An experimenter wishes to generate in air sound wave that has a dislacement amplitude of 5.50*10 m. The pressure amplitude is to be limited to 0,840 N/m. What is the minimum wavelength the sound wave can have?

Q. A sailor strikes the side of his ship just below the surface of the sea. He hears the echo of the wave reflected from the ocean floor directly below 9.0 s later. How deep is the ocean at this point? (Note: Use the bulk modulus method to determine the speed of sound in this fluid, rather than using a tabluated value.)
