Product Information
Melde’s Apparatus is a physics laboratory instrument used to investigate wave motion and the formation of stationary waves in a stretched string. It helps students study the relationship between frequency, tension, vibrating length and the number of loops formed in the string.
This apparatus is suitable for physics practicals, wave experiments and educational demonstrations in schools, colleges, universities and science laboratories.
Product Overview
Melde’s Apparatus is commonly used to demonstrate stationary waves and resonance in a stretched string. When a string is vibrated at a suitable frequency, waves travelling along the string can combine to produce a stationary wave pattern consisting of nodes and antinodes.
The experiment allows students to investigate how the vibrating length, applied tension and driving frequency affect the wave pattern. It provides a practical understanding of the principles of wave propagation and mechanical vibrations.

Working Principle of Melde’s Apparatus
Melde’s Apparatus works on the principle of superposition of waves. When a stretched string is driven by a periodic force, waves travel along the string and reflect from its ends. Under suitable conditions, the incident and reflected waves combine to form a stationary wave pattern.
A stationary wave contains nodes, where displacement is minimal, and antinodes, where displacement is maximum. The pattern depends on the vibrating length, string tension, mass per unit length and driving frequency.
Wave Speed Relationship:
v = ?(T/?)
Here, v represents wave speed, T is the tension in the string, and ? is the mass per unit length of the string.
Stationary Wave Condition:
L = n?/2
For a string with nodes at both ends, L is the vibrating length, ? is the wavelength, and n is the number of loops in the stationary wave pattern.
