Like many of today's great inventions, the microwave oven was a by-product of another technology. It was during a radar-related research project around 1946 that Dr. Percy Spencer, a self-taught engineer with the Raytheon Corporation, noticed something very unusual. He was testing a new vacuum tube called a magnetron (we are searching for a picture of an actual 1946 magnetron), when he discovered that the candy bar in his pocket had melted. This intrigued Dr. Spencer, so he tried another experiment. This time he placed some popcorn kernels near the tube and, perhaps standing a little farther away, he watched with an inventive sparkle in his eye as the popcorn sputtered, cracked and popped all over his lab.
The next morning, Scientist Spencer decided to put the magnetron tube near an egg. Spencer was joined by a curious colleague, and they both watched as the egg began to tremor and quake. The rapid temperature rise within the egg was causing tremendous internal pressure. Evidently the curious colleague moved in for a closer look just as the egg exploded and splattered hot yolk all over his amazed face. The face of Spencer lit up with a logical scientific conclusion: the melted candy bar, the popcorn, and now the exploding egg, were all attributable to exposure to low-density microwave energy. Thus, if an egg can be cooked that quickly, why not other foods? Experimentation began...
Dr. Spencer fashioned a metal box with an opening into which he fed microwave power. The energy entering the box was unable to escape, thereby creating a higher density electromagnetic field. When food was placed in the box and microwave energy fed in, the temperature of the food rose very rapidly. Dr. Spencer had invented what was to revolutionize cooking, and form the basis of a multimillion dollar industry, the microwave oven
What else can I help you with?
Which uses less energy conventional ovens or microwave ovens?
Microwave Ovens
Were microwave ovens banned in Japan?
No, microwave ovens are extremely popular in Japan.
Did they have microwaves ovens and play stations in 1940?
No, microwave ovens and PlayStation consoles did not exist in 1940. Microwave ovens were invented later, with the first commercially available model introduced in the late 1940s. PlayStation, on the other hand, was first released by Sony in 1994, long after 1940.
Do microwave ovens use electromagnetic radiation?
Yes, microwave ovens use electromagnetic radiation.
Is it true that the use of microwave ovens is banned in Germany?
No, it is not true that the use of microwave ovens is banned in Germany.
What are some features of cheap microwave ovens?
Some features of cheap microwave ovens are that they can cook things at very high temperatures and some newer microwave ovens even have a convection feaure on them.
Are microwave ovens made in a standard length?
No, microwave ovens don't have a standard length. They come in different sizes.
Is there UV in microwave ovens?
No, microwave ovens do not emit ultraviolet (UV) radiation. They use microwave radiation to heat and cook food by causing water molecules in the food to vibrate, generating heat. UV radiation is not involved in the operation of microwave ovens.
Many people use microwave ovens to cook their food. Which option is best described as an engineering endeavor related to microwave ovens?
Researching the way people use microwave ovens to determine how to improve their design
Is there any radioactive material in microwave ovens?
There are no radioactive materials in microwave ovens: they use microwaves to cook food and heat liquids.
How did people cook their food 100 years ago?
Same as today, with ovens and stoves. The exception being microwave ovens which were invented later. Note: the electric stove was first introduced in 1893. The microwave oven in 1947.
