![]() When the tuning fork is hit with a rubber hammer, it begins to vibrate to calculate the levels of water, we need to calculate the length for two cases of resonance. The air column in the pipe resonates with a tuning fork of frequency 500 Hz, when the minimum length of the air column is 15.5 cm.Find the speed of sound in air at room temperature. ![]() Therefore, the levels of water are 75cm and 25cm when the sound of the tuning fork is intensified.Ī tuning fork serves as a useful illustration of how a vibrating object can produce sound. In a resonance tube experiment to determine the speed of sound in air, a pipe of diameter 5 cm is used. Have the students place the vibrating turning fork in a cup of water and then answer question 10. Students will answer 8c and 9 based on the information about the frequencies of tuning forks. That can be obtained by subtracting the two calculated lengths from 100. Hold the tines firmly in your hand to silence the fork before beginning the test. We have to calculate the levels of water for both cases. Since the sound of the tuning fork is intensified at resonance. Our unweighted forks use a proprietary prepared alloy of aluminum and give off wonderful overtones and harmonics.
