But for me it was disappointing because I know it is actually possible to see what radio waves look like ... this radar to directly image a 2.4 GHz microwave field emitted from its own transmitter.

The electromagnetic spectrum has many types of light waves. It includes radio waves, microwaves, infrared light, visible light, ultraviolet, X-rays, and gamma rays. Each type of light has a different ...

Radio waves have wavelengths ranging from thousands of metres down to around 30 cm. This means they can easily travel around large objects, like hills, mountains or buildings. Microwaves have ...

There's lots to discover in the electromagnetic spectrum. Here's a tour that begins with radio waves and takes you through microwaves, infrared radiation, light, ultraviolet radiation, and X-rays.

Magnetrons cause electric charges to oscillate and emit microwaves — a more powerful form of radiation than the radio waves previously used for radar defences. The post-war period saw a ...

The question “are we alone in the universe?” has fascinated people for centuries. In 1959 two Cornell University physicists described how we might answer that question through interstellar ...

Since their introduction in 1967, microwave ovens have become an essential appliance in kitchens both commercial and residential. These devices produce a type of electromagnetic radiation known as ...

“The theories are now that the radio wave burst might be linked to a very ... the radio interference was recently discovered to be coming from a microwave oven located by the Parkes telescope ...

Terahertz electromagnetic waves occupy a middle ground between electronics waves, like microwave and radio waves, and photonics waves, such as infrared and UV waves. For example, mobile phones use ...
