Melde's experiment used for creating standing waves on a vibrating string in the Physics Experimental Labs. 

The experiment shows how resonance occurs in a mechanical system and how it can be used to determine the frequency of a vibrating object. The setup involves a string that is clamped at both ends and connected to a mechanical oscillator that drives the string at a fixed frequency. 
As the oscillator frequency is increased, (or mass on pan increased) the string begins to vibrate in a standing wave form where one can easily see nodes and antinodes.

By Increasing the mass on pan or adjusting the oscillator frequency one can easily obtain the natural frequency of the string. Hence, the amplitude of the vibration increases suddenly that is the result of resonance phenomenon. Melde's experiment helps to demonstrate of complex wave phenomena, e.g., standing waves, nodes-antinodes, acoustics resonance, Wave interference, harmonic motion, wave patterns, etc. that is used in physics education to teach concepts of physics.
