Melde’s Apparatus
Model Number: MTW-08
Melde’s Apparatus is a laboratory instrument designed to demonstrate vibrations in a stretched cord and investigate the relationship between frequency, tension, vibrating length, and linear density. Micro Technologies supplies the apparatus with an adjustable length of thin steel rod mounted in socket terminals, an AC energizing coil, permanent magnet, armature arrangement, adjustable contacts, and suitable cord attachment. The system produces controlled mechanical vibrations that can generate observable standing-wave patterns in a stretched cord. Two adjustable contacts are provided on either side of the armature and connected to terminal sockets, allowing the arrangement to be adapted for suitable switching, capacitor charge/discharge, and related experimental configurations. The apparatus provides a versatile setup for practical investigations of vibration and wave behaviour.
Product Specification
The Melde’s Apparatus is designed for practical investigation of vibrations produced in a stretched cord. It provides a controlled experimental arrangement for observing standing-wave patterns and studying how the behaviour of a vibrating string or cord depends on variables such as frequency, tension, vibrating length, and linear density.
The apparatus incorporates an adjustable thin steel rod mounted in a pair of socket terminals near one end. The rod passes through an AC energizing coil and is influenced by a permanent magnet. When the electromagnetic arrangement is energized, periodic motion is produced and transferred to the attached cord.
At the free end of the steel rod, a small boss with a clamping screw is provided for attaching the cord securely. The cord can then be stretched under suitable tension so that vibrations generated by the electromagnetic system travel along its length.
Under appropriate combinations of frequency, length, and tension, stationary or standing-wave patterns can be formed. These patterns allow nodes and antinodes to be observed and provide useful experimental data for investigating fundamental relationships in transverse wave motion.
Micro Technologies supplies the apparatus with two adjustable contacts positioned on either side of the armature. These contacts are connected to terminal sockets and can be used for suitable switching arrangements and capacitor charge/discharge experiments where required.
The adjustable configuration allows experimental conditions to be modified systematically. By changing the effective vibrating length, applied tension, or excitation conditions, users can compare the resulting wave patterns and examine the factors controlling the frequency of a stretched cord.
Its combined electromagnetic and mechanical arrangement makes Melde’s Apparatus a versatile laboratory solution for experiments involving resonance, transverse vibrations, stationary waves, frequency, tension, and string dynamics.

FAQs
What is Melde’s Apparatus used for?
Melde’s Apparatus is used to investigate vibrations and standing waves in a stretched cord and to study relationships involving frequency, tension, vibrating length, and linear density.
What type of waves can be observed?
The apparatus can produce standing transverse-wave patterns in a suitably stretched cord, allowing nodes and antinodes to be observed.
How are vibrations generated in the apparatus?
An AC energizing coil and permanent magnet interact with the steel rod or armature arrangement to produce periodic mechanical vibrations.
What is the purpose of the clamping screw?
A small boss with a clamping screw is provided at the free end of the vibrating rod for securely attaching the experimental cord.
Can the effect of tension be investigated?
Yes. By changing the tension in the stretched cord while controlling other experimental parameters, its effect on the vibration frequency and standing-wave pattern can be investigated.
Can vibrating length be varied?
Yes. The experimental arrangement allows the effective vibrating length to be adjusted so its relationship with frequency and standing-wave formation can be examined.
What are nodes and antinodes?
Nodes are positions of minimum displacement in a standing wave, while antinodes are positions where the vibration amplitude is maximum.
What are the adjustable contacts used for?
Two adjustable contacts are provided on either side of the armature and connected to terminal sockets. They can support suitable switching arrangements and capacitor charge/discharge experiments.
Does Melde’s Apparatus require a power supply?
Yes. A suitable external electrical supply is required to energize the electromagnetic vibration arrangement. The exact supply should match the apparatus configuration.
What additional equipment may be required?
Depending on the experiment, a suitable cord, masses or weight set, balance, power source, and measurement accessories may be required.
How should the apparatus be maintained?
Keep the mechanical and electrical components clean and dry, inspect terminal connections regularly, and ensure the vibrating rod, clamping arrangement, and contacts remain correctly aligned.
Can Melde’s Apparatus be ordered in bulk?
Yes. Micro Technologies can supply Melde’s Apparatus in bulk for physics laboratories, universities, colleges, research facilities, scientific equipment distributors, and institutional projects.
