The microwave oven was invented after a researcher Percy Spencer walked by a radar tube and a chocolate bar melted in his pocket.

Cooking food with microwaves was discovered by Percy Spencer while building magnetrons for rader sets at Raytheon. He was working on an active radar set when he noticed a strange sensation, and saw that a peanut chocolate bar he had in his pocket started to melt. Although he was not the first to notice this phenomenon, as the holder of 120 patents, Spencer was no stranger to discovery and experiment, and realized what was happening. The radar had melted his candy bar with microwaves. That was a quote from the Wikipedia article. A link is provided.

In 1945 engineer Percy Spencer was researching radar at the Raytheon Company when he stopped in front of a magnetron, and noticed the chocolate bar in his pocket was melting. Spencer and other engineers at Raytheon went on to develop the first microwave oven.

Radar was the new invention that was used to detect aircraft during World War II. It uses radio waves to detect the presence, direction, and speed of objects, including aircraft, by sending out pulses of electromagnetic waves and analyzing the echoes that bounce back.
Radar was significant in the detection of the Luftwaffe.
