The ESAW Bell Experiment Apparatus (SM-3658) is a trusted demonstration tool for explaining the principles of sound propagation and the effect of air medium on sound transmission. Widely used in physics classrooms, this apparatus visually and audibly demonstrates how sound cannot travel through a vacuum, reinforcing foundational acoustics concepts.
Designed for high-clarity classroom demonstrations, this unit includes a bell mounted within a transparent jar. When air is pumped out (via vacuum pump, not included), the bell's sound fades—perfectly illustrating the dependence of sound waves on medium. An affordable bell experiment apparatus for labs, it is ideal for practical learning.
This model is ideal for:
-
Students and science educators needing visual experiments for acoustics
-
School and college physics labs for daily demonstrations
-
Engineering and nursing colleges to teach wave properties and vacuum behavior
-
Science museums, industrial training labs, and international educational institutions
Manufactured in India by ESAW, this is an export-quality physics apparatus recognized across Africa, the Middle East, Asia, and the Americas.
