What are microwaves and radio waves?
Ans: Microwaves:
1. The wavelength ranges from 10μm to10m
2. Commonly produced by Electromagnetic oscillators of high frequency
3. Used in telemetry microwave ovens and satellite communication
Radio waves:
1. The wavelength ranges from 1m to about 100km
2. Produced when electrons are accelerated in a suitable electronic circuit.
3. Used in carrying messages to long distances and in radio astronomy.
