- Tuning Fork
- Rubber/Cork
Procedure:
1. Hold the tuning fork by its stalk and strike the prongs gently against a rubber or cork surface, such as an eraser.
2. Once struck, bring the tuning fork close to your ear and you should hear a clear, sustained tone.
3. The frequency of the sound produced by the tuning fork will be determined by the physical characteristics of the fork, such as its length, width, and thickness.
Explanation:
When the tuning fork is struck, the prongs vibrate and create sound waves. The rubber/cork acts as a damping material, preventing the prongs from vibrating excessively. The frequency of the sound produced is directly related to the rate at which the prongs vibrate, which in turn is determined by the physical properties of the fork.
