Melde’s String Apparatus Melde’s String experiment is an elegant way to introduce students to the concept of standing waves. The apparatus consists of a string and an oscillator to generate different frequencies. Melde’s experiment is ideal to study the behavior of standing waves. Students can ev...

Demonstrates that sound waves need material medium for propagation and cannot travel through vacuum. For use on pump plates with diameter at least 15cm. It consists of an electric Bell operating on 4-6 volts AC/DC, suspended inside bell jar through a pair of thick metal wires from a rubber bung t...
