What has the author George Briggs Collins written?
George Briggs Collins has written: 'Microwave magnetrons' -- subject(s): Magnetrons
Microwaves are produced by?
Microwaves are produced by electronic devices called magnetrons, which convert electrical energy into microwave radiation. This radiation heats and cooks food by exciting the water molecules within it.
When was the first microwave invented and by whom?
An engineer named Percy Spencer, who was involved with the construction of magnetrons for use in radar. (A magnetron is the microwave generating part of a microwave oven.) He worked for Raytheon, and when he found a melted chocolate bar partially melted in his pocket, he deduced that leaking microwave energy was the cause. To test his theory, he put food in a metal box and microwaved it, and it heated up very quickly. On the 8th of October, 1945, Raytheon filed for a patent, and the microwave oven was born.
How were microwaves created in science?
Microwaves were discovered as a form of electromagnetic radiation in the early 20th century by scientists studying radio waves. They were later harnessed for practical use with the invention of the microwave oven by Percy Spencer in the 1940s. Microwaves are produced by electronic devices like magnetrons, which generate electromagnetic radiation in the microwave frequency range.
Why is mercury used in microwaves?
Mercury is not used in microwaves. Microwaves use magnetrons to generate microwave radiation, which heats food by causing water molecules to vibrate. Mercury is a toxic element and is not safe for use in consumer products like microwaves.
how are microwaves radiation produced?
High power (microwave ovens, communication satellites, etc) are generated by magnetrons (used in microwave ovens), klystrons, traveling-wave tubes (TWT), and gyrotrons. Low power uses are generated by transistor oscillators (usually FETs).
What are the appliances that uses electromagnet?
Some common appliances that use electromagnets include refrigerators (for compressors), washing machines (for motors), electric fans (for motors), and microwave ovens (for magnetrons). Electromagnets are also found in speakers, MRI machines, doorbells, and some power tools.
Are thickening agents interchangeable?
No they are not interchangeable
What year was the microwave oven and the typewriter invented?
Microwave Oven:The microwave oven was invented accidentally (did you ever notice that most great inventions or occurrences are accidents? 8>0 ) by Percy Spencer in Waltham, Massachusetts. Spencer was actually given the task of making magnetrons for radar sets for the Raytheon company, and he gave a microwave to them instead! The first microwave oven was presented to the public by the Raytheon Company in 1947, and it was a bulkier, much more energy consuming device that the modern one today, weighing 700 pounds! The ovens weren't very popular in the '50s and '60s, but in the early '70s, they sold faster than ice cream on a blazing day! In 1975, one MILLION microwaves were sold!! Typewriter:The first useful typewriter was made by Christopher Latham Sholes in 1868.
Why were microwaves banned in Russia?
There was no law that banned microwave ovens in the old Soviet Union, William Kopp made this up for his article many years ago. Several debunkers have trawled the USSR legal code without success trying to find the law - or the law that repealed it during perestroika. One argument goes that if even the Soviets banned microwave ovens, and we all know how evil the Soviets were, then surely microwave ovens must be bad. It is in the same boat as the allegation that the Nazis invented microwave ovens. They didn't (if they had cavity magnetrons available, they would have done what the British did and built accurate high frequency radar sets). Evil inventors developing something that even the evil Soviet empire had to ban, how effective that is as anti microwave oven propaganda. The question is valid given the sheer bulk of comment on the internet, but the simple truth is that microwave ovens were not banned in the old USSR. Urban Myth. No evidence whatsoever to support it.
The protoplasm and cytoplasm of a plant are interchangeable terms.?
No, they are not interchangeable.
What a microwave can do?
A microwave is, in fact, a microwave
