WHO INVENTED THE MICROWAVE? The First Radarange In 1947, Raytheon demonstrated the world's first microwave oven and called it a Radarange, the winning name in an employee contest. Housed in refrigerator-sized cabinets, the first microwave ovens cost between $2,000 and $3,000.

How Do Microwaves Cook Food? Microwaves are electromagnetic waves that fly through space at the speed of light. We can't see microwaves, but if you could, you would see the microwave cooking chamber light up with an intense glow. Microwaves are shorter than radio waves but longer than infrared radiation. The microwave used for cooking is about 12 centimeters from crest to crest, says Louis Bloomfield, a professor of physics at the University of Virginia. At this wavelength, microwaves are readily absorbed by most foods. But the particles in a microwave, known as photons, don't have enough energy to damage molecules and cause cancer like ultraviolet rays or X-rays. Microwaves are sandwiched between radio waves and infrared light on the electromagnetic spectrum.

11 Surprising Facts and Myths About Microwave Ovens Most microwave ovens hit food with microwaves at a frequency of 2.45 gigahertz (GHz) (a wavelength of 12.24 centimetres (4.82 in)). The prevailing belief is that molecules in the food, particularly water, absorb energy from the waves through dielectric heating.

There Was No Ban on Microwave Ovens in the USSR Los and Dumansky from the Ukraine. No mention of any ban on ovens. 1977; 1979; At conferences on microwave bioeffects in Airlie , Virginia and Seattle, WA extensive discussions are held with scientists and engineers from the USSR and no hint of an oven ban is ever mentioned.

Britain's oldest microwave still going strong after 40 years - and 150,000 meals By late 1946, the company filed a patent proposing that microwaves be used to cook food. The first one produced weighed 340kg, stood 6ft tall and cost $5,000 (£3,664). But years of work were needed to make the invention affordable and small enough for kitchens.

I Accidentally Invented Electronics in 1906 When, around 1950, vacuum tubes began to be replaced by smaller, cheaper, and more reliable solid-state transistors, the popularity of electronic appliances exploded. In the miniaturized form of the triode transistor, Lee de Forest's invention became the workhorse of our information age.

Did congress ever declare war on Iraq and if not is it true that we are not in a war? Congress doesn't have to have a declaration of war.The constitution says that congress has the power to declare war.Nothing else specific So they can declare war in whatever fashion they want.It doesn't have to be named declaration of war.They voted to authorize the Iraq war.So you can go to war.o. There are 5 wars in which the United States formally declared war against a foreign nation, namely, the War of 1812, the Mexican-American War, the Spanish-American War, World War I, and World War II.

microwave A microwave oven is activated when an electric current causes a magnetron to emit a beam of microwaves. The beam is distributed throughout the unit by a rotating reflector. The microwaves agitate water molecules in the food, generating enough heat to cook it.

- The first electric toaster was invented in 1893 in Great Britain by Crompton and Co (UK) and re-invented in 1909 in the United States. It only toasted one side of the bread at a time and it required a person to stand by and turn it off manually when the toast looked done.

Toaster In 1905, Westinghouse introduced a toaster stove that featured a heating element on a raised base. The bread was placed in a wire mesh tray that lay across the heating element. Five years later, General Electric received the first patent for an electric toaster.

Microwave Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter; with frequencies between 300 MHz (100 cm) and 300 GHz (0.1 cm).t indicates that microwaves are small, compared to waves used in typical radio broadcasting, in that they have shorter wavelengths. The boundaries between far infrared, terahertz radiation, microwaves, and ultra-high-frequency radio waves are fairly arbitrary and are used variously between different fields of study.

Who Invented Microwave Popcorn That research led to the first microwave popping bag, of which these two gentlemen named above have the patent. Even so, these first bags of microwavable popcorn were just the kernels of corn combined with a convenient popping bag. What we think of modern microwave popcorn was yet to come.

- Nearly every home has one, but microwave ovens still mystify. July 23, 2011|By Mike McClintock | Special to Tribune Newspapers. When America entered the space race in the early 1960s, a new wave of space-age products promised a leisurely future, . but only one was really different and remains somewhat mystifying: the microwave oven.

How does a microwave heat up the food? Microwaves are a form of electromagnetic energy, like light waves or radio waves, and occupy a part of the electromagnetic spectrum of power, or energy. Microwaves are very short waves of electromagnetic energy that travel at the speed of light (186,282 miles per second).

- Both Tappan and Raytheon realized the potential of a smaller sized microwave and hoped that it would take off in households around the country. In 1955 Tappan Stove Company put its first microwave on the market. It was 24 inches and cost about $1,200. Ten years later, by 1965, Tappan Stove Company put on the market the first combination conventional range and microwave oven, “this further boosted sales”.[40]. By 1976, the microwave was in 60% of homes.[6]. In fact, some say that the microwave allow vitamins to remain in food more so than if the same food was cooked using a different appliance, definitely something to keep in mind!

The History of Your Toaster Toasting bread began as a method of prolonging the life of bread. It was very common activity in Roman times, 'tostum' is the latin word for scorching or burning. The first electric toaster was invented in 1893 in Great Britain by Crompton and Co (UK) and re-invented in 1909 in the United States.

The Microwave Oven Was Invented by Accident by a Man Who was Orphaned and Never Finished Grammar School The Microwave Oven Was Invented by Accident by a Man Who was Orphaned and Never Finished Grammar School. Today I found out the microwave oven was invented by accident by a man who was orphaned and never finished grammar school. The man was Percy Spencer. At the age of just 18 months old, Spencer’s father died and his mother soon left him to his aunt and uncle. His uncle then died when Spencer was just seven years old.

Appliances in the 1920's It was during the 1920's when electric popcorn machines were manufactured and became very popular due to the start of the motion picture shows in 1917. In 1929, at the price of $1.49, electronic popcorn makers were produced for home use.

Microwave oven By 1986, 25 percent of U.S. households owned a microwave oven, up from less than one percent in 1971.4 Assuming microwave oven penetration into U.S. households was constant during this 15 year period, about 12 to 13 percent of U.S. households would have owned a microwave oven in 1978.

Who Invented Microwave Popcorn Raytheon loved the idea and so did Spencer. They realized they were onto something with the food heating that could happen and this eventually led to the invention of the microwave. Spencer himself actually holds the patent for microwave popcorn. It could be said, however, that the invention of microwave popcorn is what actually led to the invention of the microwave.

When Microwave Ovens Were New It was 6 feet tall and weighed 750 pounds. It was also water-cooled and consumed 3000 watts of power. But research continued, along with gradual miniaturization, and by the mid 50's, free-standing microwave ovens were using half as much power and cost less than $3000. That made them affordable investment by eateries and bakeries, whose operations were revolutionized by the ability to cook much faster.
