Who invented the microwave and why?
American engineer Percy Spencer is generally credited with inventing the modern microwave oven after World War II from radar technology developed during the war. Named the “Radarange”, it was first sold in 1946.
Who discovered microwaves?
But what you might not know about your indispensable kitchen appliance is that it was invented utterly by accident one fateful day 70 years ago, when a Raytheon engineer named Percy Spencer was testing a military-grademagnetron and suddenly realized his snack had melted.
Where did the microwave originate from?
In 1946, the engineer Dr. Percy LeBaron Spencer, who worked for the Raytheon Corporation, was working on magnetrons. One day at work, he had a candy bar in his pocket, and found that it had melted. He realized that the microwaves he was working with had caused it to melt.

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.
What did Percy Spencer died of?
September 8, 1970
How do humans use microwaves?
Microwaves play an increasingly wide role in heating and cooking food. They are absorbed by water and fat in foodstuffs (e.g., in the tissue of meats) and produce heat from the inside. In most cases, this reduces the cooking time a hundredfold.
Why microwaves are called microwaves?
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.
What are 3 uses of microwaves?
Microwaves are widely used in modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication, medical diathermy and cancer treatment, remote sensing, radio astronomy, particle accelerators, spectroscopy, industrial …
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?
Raytheon had filed a patent for the microwave cooking process by 1945. Two years later, it built Radarange, the first microwave oven in the world. The Radarange was as large as a refrigerator, but heavier. The tubes in the magnetron had to be water-cooled, so plumbing installation was required.
Is microwave radiation harmful?
Microwave radiation can heat body tissue the same way it heats food. Exposure to high levels of microwaves can cause a painful burn. … Additionally, the lens of the eye is particularly sensitive to intense heat, and exposure to high levels of microwaves can cause cataracts.
What type 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.
How old is Percy Spencer?
76 years (1894–1970)
How did Percy Spencer create the microwave?
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.
