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.

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.

There have been dramatic advances in the natural sciences thanks to inventions such as telescopes and microscopes that enable ...

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 ...

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 ...

Crews installed a second microwave dish on the Reservoir Hill Park radio tower in Staunton, marking another step closer toward the regional radio’s project completion.

You reach for the microwave meal, and think ... thing was to ditch the whole concept of cooking with boring old radio waves, and just use a pile of frickin’ lasers instead.

Microwaves are shorter than radio waves but longer than infrared radiation. The microwave used for cooking is about 12 centimeters from crest to crest, says Louis Bloomfield, a professor of ...
