Apparatus for Demonstrating Waves with Elastic Springs
Apparatus for Demonstrating Waves with Elastic Springs (Product Code: SCL-349/029) is a two-spring wave demonstration set used to show longitudinal and transverse waves in school and college physics lessons. Its larger spring, 8 cm in diameter, can be extended up to 5 m across a floor or bench so pulses stay visible to a whole class, while a second 2 cm spring gives a narrower medium to compare. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Elastic Spring Wave Apparatus Used For?
Two students hold the ends of the large spring and stretch it along the floor. A quick sideways flick sends a transverse pulse along the coils, while a sharp push and pull along the axis sends a band of compressed coils travelling down the spring — a simple sound wave experiment that shows how air is squeezed and stretched as sound passes through it.
With one end held firmly, pulses can be seen reflecting and returning, and steady shaking at the right rate builds a standing wave. Because the springs differ in diameter and length, the 2 cm spring gives a second medium for comparing how pulses travel. Stretch the springs gradually, keep them off sharp edges, and release the tension slowly so the coils do not tangle.
What to Specify When Ordering
- How many sets you need — one for the teacher’s bench, or one per student group for hands-on work.
- Whether you need both springs (8 cm and 2 cm) or extra springs of one size for group practicals — ask us.
- The delivery city or country, so packing and freight can be quoted with the apparatus.
OEM Manufacturer
This spring wave set is manufactured by Jain Scientific Equipments Private Limited, the company behind the ScienceLab name, acting as OEM (original equipment manufacturer). Production takes place at its own licensed factory at Saha, Ambala, Haryana, India. Because buyers deal with the maker rather than a trading intermediary, requests for additional springs or repeat supply for new laboratories are handled by the same team — ask us. Company details are on the ScienceLab profile page.

Frequently Asked Questions
What springs come with the Apparatus for Demonstrating Waves with Elastic Springs?
The Apparatus for Demonstrating Waves with Elastic Springs has two springs. Spring 1 is 8 cm in diameter, 13 cm long as listed, extends up to 5 m and weighs 0.6 kg; Spring 2 is 2 cm in diameter, 1 m long and weighs 0.5 kg.
How far can the large spring be stretched?
The large spring of the Apparatus for Demonstrating Waves with Elastic Springs can be extended up to 5 m. Keep within that length and stretch it gradually, because pulling a spring beyond its range can permanently open the coils and spoil later demonstrations.
How are transverse and longitudinal waves made with the springs?
With the Apparatus for Demonstrating Waves with Elastic Springs stretched out, a sideways flick of one end makes a transverse wave, while pushing and pulling the end along the spring’s length makes a longitudinal wave of compressions and rarefactions.
Who manufactures the Apparatus for Demonstrating Waves with Elastic Springs?
The Apparatus for Demonstrating Waves with Elastic Springs is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory at Saha, Ambala, Haryana, India, and is sold factory-direct to schools, colleges, dealers and importers.
How should the elastic springs be stored?
Store the Apparatus for Demonstrating Waves with Elastic Springs with each spring fully closed and tied loosely so the coils cannot tangle. Keep the springs dry and away from heavy objects that could bend individual coils.
What information is needed for a quotation?
To quote the Apparatus for Demonstrating Waves with Elastic Springs, ScienceLab needs the number of sets, any extra springs required and the delivery location in India or abroad. Send these details through the contact page.
