Microwaves are electromagnetic waves that are smaller in wavelength than radio waves and infrared waves. This makes microwaves more convenient for wireless transmission. They are also used in satellite communication, radar, and other applications.
Microwaves can be transmitted over short distances, but their attenuation increases as the frequency increases. For example, a microwave that has a frequency of 5 GHz will be attenuated by a half mile or more. Similarly, a microwave with a frequency of 100 GHz will be attenuated by an entire kilometer.
Microwaves can also be focused on a narrow beam. This feature is important in many industries, such as medical diathermy and spectroscopy. In addition, microwaves are widely employed in cooking. A microwave oven has a metal wall that reflects the microwave.
Other uses of microwaves include cooking, drying, and curing rubber, wood, and plastic. Microwaves can be used in radar systems to detect the distance and range of objects.
Microwaves can be detected by radar, which is used by air traffic, ships, and weather forcasters. Microwaves are also used in collision avoidance systems.
Microwaves can also be used in radar for detecting and tracking storms. Unlike radio and infrared, microwaves do not bounce off the ionosphere. Therefore, they can be used to detect oncoming vehicles.
During the late 1800s, microwaves were discovered alongside radio waves. However, they were considered useless until 1937. Scientists were working on low noise antennae at the time.
Today, microwaves are everywhere. They are used in television, cell phone signals, point-to-point communications, medical treatment, and industrial heating.
