Air in a tube closed at one end vibrates in resonance with tuning fork whose frequencies are 210 and 350 vibrations/s, when the temperature is 20°C. Explain how this is possible and find the effective length of the tube. Assume that the velocity in air at 0°C is 33, 150 cm/s.

Solution:
Air in a tube closed at one end vibrates in resonance with tuning fork whose fre
