Radio waves and microwaves:

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.
