These wavelengths are shorter than the radiation used in commercial radio broadcasting but longer than the wavelength of infrared radiation. However, these boundaries are arbitrary since the properties of the waves change gradually rather than abruptly with changing frequency.
Microwaves have a number of applications, such as microwave ovens, radar, and telecommunications.
Microwave ovens are used to heat foods by penetrating it with short radio waves. These waves cause the molecules in the food to vibrate rapidly, creating friction among the moving molecules, which creates heat, which cooks the food. In telecommunications, microwaves are used to carry information for telephone and television systems. The first advantage of using microwaves in radar and telecommunications is that they can easily pass through rain, smoke, fog, as well as through the ionosphere which blocks or reflects longer radio waves. The second advantage is that microwaves, which have a higher frequency than radio waves, can carry more information as the frequency increases.
