Apparatus for Demonstrating the Propagation of Waves (Product Code: SCL-351/028) is a mechanical wave machine used to show how transverse and longitudinal waves travel, in school and college physics classrooms. Teachers use it to make wave motion visible: a handle turns a row of eccentric discs that move a series of metal rods across a 450 mm x 200 mm x 300 mm working range. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

In a wave motion lesson, the teacher turns the handle slowly so students can watch each rod rise and fall in turn while the disturbance itself moves along the row. The rods only move up and down, yet the pattern travels sideways — the defining idea of a transverse wave. The bent rods then show compressions and rarefactions moving in the direction of travel, the model students later apply to sound in air.
Seeing both wave types on one frame helps learners compare amplitude, wavelength and the direction of particle motion side by side. Turning the handle faster raises the frequency and the pattern moves along more quickly, a practical way to introduce the link between wave speed, frequency and wavelength. As school physics lab equipment, it is easiest to follow at eye level on a raised bench, with a chalk mark on one rod so the class can track a single particle.
Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM (original equipment manufacturer) of this wave propagation apparatus. It is made and assembled at the company's own licensed factory at Saha, Ambala, Haryana, India, rather than bought in from a trader. Schools, colleges, dealers and importers therefore deal directly with the maker, and questions about replacement rods, pulleys or repeat orders can be raised with the same team — ask us.

What does the Apparatus for Demonstrating the Propagation of Waves show?
The Apparatus for Demonstrating the Propagation of Waves shows both transverse and longitudinal waves. Eccentric discs turned by a handle move a series of metal rods to form a transverse wave, while the bent rods produce a longitudinal wave for comparison.
How large is the working area of this wave apparatus?
The wave propagation range of the Apparatus for Demonstrating the Propagation of Waves measures 450 mm x 200 mm x 300 mm, a size a teacher can operate on the front bench while the whole class watches. Ask us for the packed size when planning shipping.
Does the wave propagation apparatus need a power supply?
The listing for the Apparatus for Demonstrating the Propagation of Waves gives voltage values of 0–6 V and a 15.6 mm vibrator alongside the hand-turned mechanism. Tell us how you plan to power it and we will confirm the supply it needs and whether one is included.
Who manufactures the Apparatus for Demonstrating the Propagation of Waves?
Jain Scientific Equipments Pvt Ltd (ScienceLab) is the OEM manufacturer of the Apparatus for Demonstrating the Propagation of Waves. It is made at the company's own factory at Saha, Ambala, Haryana, India, and supplied direct to institutions, dealers and importers.
Which classes is this wave demonstration apparatus suited to?
The Apparatus for Demonstrating the Propagation of Waves suits secondary school and college physics lessons on wave motion, where students must tell transverse from longitudinal waves before moving on to sound, light and the wave equation.
Can the wave propagation apparatus be ordered in bulk or for export?
Yes. ScienceLab supplies the Apparatus for Demonstrating the Propagation of Waves for single laboratories, multi-school projects and dealer stock in India and international markets. Share the quantity and destination through the contact page for a quotation.
