Microwaves
Microwaves are a type of electromagnetic wave with wavelengths ranging from about one meter to one millimeter. They are commonly used in communication, cooking, and various scientific and medical applications.
Properties of Microwaves
- Wavelength: Microwaves have wavelengths between infrared radiation and radio waves.
- Uses: They are commonly used in microwave ovens for cooking food, in radar systems for communication and detection, and in telecommunications.
- Interaction with Matter: Microwaves can penetrate through many materials, and are absorbed by water, fats, and sugars, leading to heating effects.
- Sources: Microwaves are produced by specialized electronic vacuum tubes such as klystrons and magnetrons, and also by solid state devices such as Gunn diodes.
