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. The set is manufactured by Science Lab Supplies at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, which quotes it directly to schools, colleges, tender contractors and distributors.
Specifications
The transmitter houses a Gunn diode in a cylindrical case 83 mm across and 70 mm long, 225 mm long overall, and the receiver follows the same construction. A silicon-diode probe on a short non-metallic rod maps the field, while aluminium and acrylic mirrors and a mesh handle reflection and polarisation.

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.
- Law of reflection with the aluminium mirrors 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 and two BNC cables.

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, which suits bench-scale experiments.
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.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies manufactures this microwave set in its Saha, Ambala factory, and the quotation you receive comes straight from that factory rather than from an agent.
