Guided Notes
3 key concepts
- 1
In the experiment, sand is sprinkled on a metal plate to visualize the vibration patterns when sound is produced.
- 2
The patterns revealed by the sand occur at a natural frequency of the metal plate, which contributes to the overall sound.
- 3
Each vibrating object has its own combination of natural frequencies, determined by its physical characteristics, forming a unique acoustic signature.
