G3-31: Spring and Horns
- ID Code: G3-31
- Purpose: To audibly illustrate transmission of energy in a mechanical wave
- Description:
This long spring has a horn mounted on each end, which amplifies the vibrations from the spring as they pass into the air. Invite a student volunteer to hold each end, and show how energy is transferred through a wave and produces sound at the far end of the spring.
This demonstration was donated by Prof. William Dorland.
