Chapter 5: Problem 63

Describe an experiment to prove that sound is produced by vibrating bodies.

Short Answer

Expert verified

Answer: The 'Tuning Fork Experiment' demonstrates the production of sound by vibrating bodies by striking a tuning fork with a rubber hammer, causing it to vibrate and produce sound. As the vibrations slow down, the sound decreases until it stops, showing the direct relationship between the vibrating body and the sound produced. To visualize the vibrations, touching the surface of a table or placing a piece of paper on the vibrating fork reveals the movement caused by the vibrations and the resulting sound.

Step by step solution

Experiment Description

One easy and commonly known experiment to support this statement is the 'Tuning Fork Experiment.' In this experiment, a tuning fork is used to demonstrate how vibrating bodies produce sound. The materials required are a tuning fork, a rubber hammer, and a surface like a table.

Striking the Tuning Fork

Strike the tuning fork with the rubber hammer, which will cause it to vibrate. Observe the sound produced by the tuning fork when it's vibrating.

Vibration and Sound Relationship

Listen carefully to the sound produced. As the vibrations of the tuning fork slow down, the sound will gradually decrease until it finally stops. This shows the direct relationship between the vibrating body and the sound produced.

Visualizing the Vibration

To visualize the vibrations, gently touch the surface of a table, or put a piece of paper (carefully without tearing) on the vibrating tuning fork. You will feel or see the movements as the tuning fork vibrates and makes contact with the surface or the paper. The vibrations are transferring from the tuning fork to the table or paper, producing sound. Through this simple tuning fork experiment, it is evident that sound is produced by vibrating bodies. As the tuning fork vibrates, it creates sound waves that we can hear. When the vibrations cease, the sound stops.
