Propagation Of Sound In Solid Bodies Manufacturer,Supplier and Exporter in India
Product Code : EL-TLT-13043
Quick Answer: Propagation Of Sound In Solid Bodies is a physics experiment that uses a tuning fork to show that sound travels through solids such as a plastic ruler, the human head and a thin thread as well as through air.
Last updated: October 2026
Key Features
- Tuning fork placed on one end of a solid body to set it oscillating
- Oscillation propagates to the other end of the solid body
- Transmission heard directly at the other end or through the air
- Examples: a plastic ruler, the human head and a thin thread
- Tuning fork sound no longer heard, or only slightly, through air at approximately 20 cm
- Conduction through solids over comparable distances lets the sound be heard clearly

About This Product
Sound is a mechanical vibration, so it needs a medium and can travel through solids, liquids and gases. In this experiment one end of a solid body is made to oscillate by touching a tuning fork to it, and the vibration passes along the body to the other end. Students compare how clearly the sound is heard through air at a distance of approximately 20 cm with how clearly it is heard through a solid over a similar distance, and find that conduction through the solid carries it better.
Frequently Asked Questions
Q1. What does this experiment show?
It shows that sound can propagate in solid bodies as well as in air, using examples such as a plastic ruler, the human head and a thin thread.
Q2. How is the sound produced and heard?
One end of the solid body is made to oscillate, for example by placing a tuning fork on it. The oscillation travels to the other end, where it can be heard directly or through the air.
