Apparatus for Demonstrating Reflection, Refraction, Polarization and Diffraction using Microwaves
Product Code : SCL-PL-11848
Apparatus for Demonstrating Reflection, Refraction, Polarization and Diffraction using Microwaves (SKU SCL-PL-11848) is a microwave optics set that lets students repeat the classic wave-optics experiments at a 2.8 cm wavelength, for senior secondary and undergraduate physics and electronics labs. Science Lab Supplies builds the whole microwave set at its factory on Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and manufactures it to order for schools, colleges, tender contractors and distributors.

Applications and Experiments for the Microwave Optics Apparatus
Because a 2.8 cm wavelength is large enough to handle with bench-sized mirrors and meshes, the apparatus lets students show that microwaves reflect, refract, polarise and diffract just as light does. It supports Class 12 electromagnetic-wave and wave-optics topics and B.Sc. or engineering microwave practicals.
- Class 12 physics: placing microwaves in the electromagnetic spectrum and measuring their wavelength, then comparing it with visible light dispersed by a Glass Prism (Equilateral, 50 × 50 mm).
- Law of reflection with the aluminium mirrors, the same law the Light Ray Reflection Demonstrator traces with light, and polarisation with the mesh.
- Diffraction and standing-wave mapping with the probe detector and multimeter in B.Sc. and engineering labs.
Run the transmitter under teacher supervision and keep faces away from its aperture during experiments.
Standard Scope of Supply
The set includes the microwave transmitter, microwave receiver, probe detector with its socket base, a power source, a diode, a speaker, the three aluminium mirrors, the acrylic mirror, the polarising mesh, a digital multimeter, a BNC T cable and a BNC cable.

Frequently Asked Questions
What frequency and wavelength does the transmitter use?
The Gunn diode transmitter works at 10.7 GHz, a wavelength of about 2.8 cm. That wavelength suits bench-scale experiments with the 300 mm mirrors and the mesh, and the matching receiver picks up the beam.
How is polarisation shown with microwaves?
The polarising mesh, 190 x 300 mm, is placed between transmitter and receiver and rotated; the received signal changes with the mesh angle, and the change can be followed on the digital multimeter included in the set.
Is Science Lab Supplies the manufacturer or a trader?
Every microwave set is built by the manufacturer, Science Lab Supplies, in its Saha, Ambala factory in India. Buyers deal with the maker directly, and no agent adds a margin to the quotation.
