How the microwave was invented by a radar engineer who accidentally cooked a candy bar in his pocket. … One day while working near the magnetrons that produced microwaves, Spencer noticed a peanut butter candy bar in his pocket had begun to melt — shortly after, the microwave oven was born.
Why did Percy Spencer invent the microwave?
Percy LeBaron Spencer, who worked for the Raytheon Corporation, was working on magnetrons. … He realized that the microwaves he was working with had caused it to melt. After experimenting, he realized that microwaves would cook foods quickly – even faster than conventional ovens that cook with heat.
What was Percy Spencer trying to make when he invented the microwave?
One day at work in 1945 Spencer was standing next to an active magnetron when a candy bar in his pocket melted. Intrigued, he sent out for unpopped popcorn. When it popped in front of the magnetron, he realized that microwaves could cook food.
How were microwaves originally invented?
Employed by Raytheon at the time, he noticed that microwaves from an active radar set he was working on started to melt a chocolate bar he had in his pocket. The first food deliberately cooked with Spencer’s microwave oven was popcorn, and the second was an egg, which exploded in the face of one of the experimenters.
What was Percy Spencer trying to make?
Percy Lebaron Spencer (July 19, 1894 – September 8, 1970) was an American physicist and inventor. He became known as the inventor of the microwave oven.

What kind of engineer was Percy Spencer?
His lack of formal education meant that he had to teach himself trigonometry, calculus, chemistry, physics, and metallurgy at night. Percy Spencer, a New England farm boy who never completed grammar school, grew up to be one of the world’s most successful and respected electrical engineers.
What did Percy Spencer died of?
September 8, 1970
When did Percy Spencer die?
September 8, 1970
How old is Percy Spencer?
76 years (1894–1970)
How did the microwave change the world?
“A relatively new technology – the microwave oven – is dramatically changing the U.S. food industry. … Microwave ovens have allowed people to cook their food in minutes making meal preparation faster. It gave people the opportunity to eat foods they might not have otherwise, especially snacks like microwavable popcorn.
What was the first microwave called?
The first microwave oven was called the Radarange, and today, there are over 200 million in use throughout the world.
Why is the microwave bad?
Microwaves do have some downsides. For example, they may not be as effective as other cooking methods at killing bacteria and other pathogens that may lead to food poisoning. That’s because the heat tends to be lower and the cooking time much shorter. Sometimes, food heats unevenly.
Why is it called microwave?
The name Microwave is derived from the energy used to cook the food, microwaves, which pass through the cells and molecules of the food, the frequency of the waves causes the water molecules to vibrate, this movement generates heat. These microwaves are produced by a device called a magnetron within the microwave oven.
Who invented microwaves?
What was the microwave supposed to be?
Spencer worked for a company named Raytheon, developing microwave radar transmitters during World War II. … He created the first working microwave oven, and the first food he cooked in it was popcorn. Microwave ovens use microwaves, which are radio waves at a frequency of approximately 2,500 megahertz, to heat food.
What is a magnetron used for?
A type of vacuum tube used as the frequency source in microwave ovens, radar systems and other high-power microwave circuits. In radar, magnetrons can be used as the signal source to feed the power stage of the radar transmitter, typically a klystron tube.
