Apparatus for demonstrating the phenomenon of wave propagation and reflection
Apparatus for demonstrating the phenomenon of wave propagation and reflection (Product Code: SCL-697/049) is a ripple-tank style physics demonstration kit used to make water waves visible so students can study how waves travel, reflect, refract and interfere in school and college physics lessons. A mechanical oscillator drives two forks that excite waves at two points on the water surface, and circular waves can also show the Doppler effect. The apparatus is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Wave Propagation and Reflection Apparatus Used For?
With a circular wave pattern, students measure the spacing between crests at several oscillator frequencies and see that the wavelength shrinks as the frequency rises. Moving the source while it vibrates bunches the crests ahead of it and spreads them behind, a clear view of the Doppler effect. Switching to plane waves and changing the water depth shows that waves travel more slowly in shallow water, which is the basis of refraction.
Placing a plate, prism or lens-shaped object in the path of plane waves shows reflection and refraction, while the small barrier and the two Young’s slits reveal diffraction and interference. Driving both forks together produces the two-source interference pattern of alternating calm and active lines. For clear results, level the tank so the depth is uniform and keep the water free of dust and bubbles.
What to Specify When Ordering
- Which obstacle pieces you need: the listing names a concave lens, a diffraction barrier and two slits, while the plate, prism and convex lens appear only in the experiment description.
- Number of apparatus sets for demonstrations or student groups.
- Your mains supply details for the oscillator.
OEM Manufacturer
This wave apparatus is an OEM product of ScienceLab, the brand name of Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597). Production takes place at the company’s licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana (Factory Licence AMB-ONLINE-CHD-J-414), from where it is supplied factory-direct to schools, colleges, institutions, dealers and importers.
Because the manufacturer quotes and ships the apparatus itself, requests for extra obstacle pieces or repeat orders go straight to the source — ask us. The ScienceLab company profile has more background.

Frequently Asked Questions
What does the Apparatus for demonstrating the phenomenon of wave propagation and reflection consist of?
The Apparatus for demonstrating the phenomenon of wave propagation and reflection consists of a water tank in which two forks excite waves at two points, a concave lens, a small diffraction barrier, two Young’s slits (listed as “Jung cracks”) and a base unit, with a mechanical oscillator generating the waves.
Which wave phenomena can be demonstrated?
The wave propagation and reflection apparatus SCL-697/049 demonstrates how wavelength depends on oscillator frequency, the Doppler effect, how wave velocity depends on water depth, and the reflection and refraction of waves. Its barrier and slits add diffraction and two-source interference.
How is the Doppler effect shown with this apparatus?
In the wave propagation and reflection apparatus SCL-697/049, a circular wave pattern is produced while the source moves. Crests crowd together in front of the moving source and spread out behind it, showing directly why an approaching source has a higher frequency than a receding one.
Are the plate, prism and convex lens included?
The experiment description for the Apparatus for demonstrating the phenomenon of wave propagation and reflection mentions a plate, prism, concave lens and convex lens, but its contents list names only the concave lens, barrier and slits. Please confirm the pieces you need through the contact page.
Who manufactures the Apparatus for demonstrating the phenomenon of wave propagation and reflection?
The Apparatus for demonstrating the phenomenon of wave propagation and reflection, code SCL-697/049, is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM at its own licensed factory at Saha, Ambala, Haryana, India, and is quoted directly by the manufacturer.
Can the wave apparatus be supplied to institutions in bulk or abroad?
Yes. The Apparatus for demonstrating the phenomenon of wave propagation and reflection can be quoted for schools, colleges, dealers and importers in India and international markets, in single units or larger quantities. Share the quantity and delivery destination when you enquire.
