When RADAR was first invented, in the 1930s, it didn't work very well because high directional accuracy required either a gigantic antenna or very short wave-lengths. Vacuum tubes had great difficulty in producing wavelengths below about 1.5 meters. In 1940 two men named Randall and Boot, working at Birmingham University in England, invented a device called a Resonant Anode Cavity Magnetron which could generate wavelengths about a thousand times shorter. Now called just a magnetron, this transformed RADAR; it has also transformed cooking, because there is at least one in almost every kitchen, inside the microwave oven.

What space technology spin-off might be used at school?
One space technology spin-off that could be used in schools is the development of water-recycling systems, similar to those used aboard the International Space Station. Schools could benefit from such technology to reduce water usage and promote sustainability in their facilities. Additionally, educational tools like virtual reality simulations developed for astronaut training could also be utilized to create engaging learning experiences for students.
Does the sun give off invisible light rays called microwaves?
No, the sun primarily emits visible light, ultraviolet light, and infrared radiation. Microwaves are a form of electromagnetic radiation with longer wavelengths than visible light, commonly associated with communication and cooking technology.
