Melde’s Apparatus Manufacturer,Supplier and Exporter in India

Product Code : SCL-EAE-14588

Indian Lab Suppliers supplies the Melde’s Apparatus (Product ID: 14588) as part of its electrical and electronics range. It sets up standing waves on a stretched string so students can relate frequency, tension, length and mass per unit length.

Quick Answer

A vibrator drives one end of a string that passes over a low-friction pulley to a weight hanger with slotted weights. Changing the tension or length gives the 1st, 2nd, 3rd and higher modes, with nodes and antinodes measured against a 0–1 m graduated scale. The frequency follows f = (p/2l)√(T/m), where p is the number of loops. The vibrator is either an electric type running on 6–12 V AC or tuning-fork driven, so please confirm the type and vibrator frequency at quotation.
