Interference of Microwaves
What is it?
Microwave interference is the variation of received microwave intensity caused by superposition of coherent microwave waves.
In simple words
- Microwave interference is a convenient large-scale demonstration of electromagnetic-wave superposition.
Recommended for Class 12
Full school-level explanation
Microwave interference is the variation of received microwave intensity caused by superposition of coherent microwave waves.
Significance
Microwaves are electromagnetic waves with wavelengths much longer than visible light. Because their wavelengths are relatively large, interference effects can be demonstrated using laboratory-scale apparatus. Two coherent microwave paths can be produced directly or by splitting/reflection. At a detector: constructive condition: Δr=nλ destructive condition: Δr=(n+½)λ Moving the detector or changing one path can produce alternating strong and weak signals. Microwave interference confirms that electromagnetic radiation obeys general wave-superposition principles.
