How the microwave oven was discovered?
The microwave oven was invented in 1947 by Percy Spencer. While working at the Raytheon Company, Mr Spencer discovered that a bar of chocolate in his jacket pocket had melted. This led to the creation of one of the most widely used household appliances.
Mr Spencer conducted research using a high-frequency generator (operating at around 60,000 MHz) for use in radar systems.
After a while, he felt a little hungry and decided to eat the chocolate bar he had found in the pocket of his jacket. However, when he took it out, he found that it had melted.
Microwave Oven History
What happened?
Mr Spencer decided to verify his experience by placing an egg and some popcorn near the frequency generator before leaving the area. When he returned to his laboratory, he found that there was popcorn and scrambled eggs everywhere.
The first microwave ovens were commercialised in 1947. These ovens were very large and were only purchased by restaurants. Since the 1970s, smaller, cheaper microwave ovens have appeared on the market and have become very popular.
In 1947, a bar of melted chocolate turned a radar into the world’s first microwave oven.
