'Microwaves' were first produced and studied by Hertz in 1886. However, their practical application was realised only on creating suitable generators.

Microwaves have wavelengths more than that of infrared waves, but less than that of radio waves.
Microwaves can penetrate clouds of smoke,haze, light rain and snow, hence used to transmit information.
The longer waves are used for heating our food, Shorter microwaves are used for mapping meteorologic disturbances and in weather forecasting.
Microwave technology is highly efﬁcient in converting electricity into MicroWaves and saves energy with rapid, in-depth heating of materials
In a Microwave oven, the waves generated are of a frequency that can be absorbed by the water and fat in the food. Microwave ovens are becoming a very popular means of heating and cooking food quickly. Check out here how a microwave oven works....
Radar is an application of microwave technology - to detect objects by transmitting short bursts of microwaves and measuring the strength and origin of "echoes" received from them.

" Beyond certain temperatures, microwaves can harm living tissue - hence prolonged exposure should be avoided "
"In extreme cases, the chemical balance of the brain can be upset if the frequencies equal the brain wave frequencies. "
What do studies reveal about the above two statements ? Read more from the links below...
Did you know that if you had a sensitive microwave telescope in your house that you would detect a faint signal leaking out of your microwave oven, and from various other man-made sources, but also a faint signal coming from all directions that you pointed it? This is the Cosmic Microwave Background!
