A steel tube, which is closed at both ends, is filled with air. The air in the tube is vibrating at a frequency of 200·Hz. Use 340·m/s for the speed of sound in air.

(a) What is the wavelength of the sound waves in the tube? _____ m.

(b) If the 200·Hz vibration respresents the fundamental standing wave for the tube, how long is the tube? _____________ m.

(c) If the air in the tube is replaced with a different gas, the frequency of the fundamental standing wave changes to 160·Hz. What is the speed of sound in this new gas? ___________m/s.
