Imagine you are holding a tuning fork of frequency 440 Hz over the top of a tube in water. Adjusting the height of the tube from shorter to longer, you hear the first loud sound when the tube is 18.6 cm long above the water as resonance occurs. You can use this information to calculate the speed of sound in air, since air is the medium for the sound wave to propagate in the tube. 1. A small amount of air above the tube vibrates as well as the air in the tube, so you need to calculate a corrected length for the tube. The correction factor is to add 0.3 times the diameter of the tube to its length. If the tube diameter is 3 cm, calculate the corrected length of the tube for vibrating air molecules using the length from above.

How to solve this question 

Imagine you are holding a tuning fork of frequency 440 Hz over the top of a tube in water. Adjusting the height of the tube from shorter to longer, you hear the first loud sound when the tube is 18.6 cm long above the water as resonance occurs. You can use this information to calculate the speed of sound in air, since air is the medium for the sound wave to propagate in the tube. 1. A small amount of air above the tube vibrates as well as the air in the tube, so you need to calculate a corrected length for the tube. The correction factor is to add 0.3 times the diameter of the tube to its length. If the tube diameter is 3 cm, calculate the corrected length of the tube for vibrating air molecules using the length from above. Fig. 1. Tube in water.
