The microwaves from the radar set he was working on were cooking the candy bar in his pocket! With a little experimentation, Spencer figured out that the microwaves could be concentrated to heat food . He created the first working microwave oven, and the first food he cooked in it was popcorn.
Read moreWhy is the microwave invention important?
Summary. In summary, the microwave oven is a brilliant invention, which makes our lives so much easier . Microwaves can reheat food in a small amount of time, keeps the essential nutrients, and doesn’t make your food soggy.
Read moreHow did the invention of the microwave change the world?
However, when the microwave oven was introduced, leftovers provided for easy meals . Suddenly, microwave ovens allowed for leftovers, meaning that someone didn’t have to cook everyday. Now, meals could stay in the refrigerators remain for a few days, and be easily heated up.
Read moreHow do microwaves work physics?
The magnetron generates microwave radiation by bouncing electrons around inside a vacuum filled cavity that is exposed to a strong magnetic field . This magnetic field forces these electrons to circle around inside the cavity, absorbing energy. Eventually, this energy is released as a microwave.
Read moreWhat is the principle of microwave?
The principle of microwave cooking is conversion of electromagnetic energy into thermal energy within meat . During cooking, microwave energy is absorbed by rotation of water molecules and translation of ionic components in meat; the water content and the dissolved ion content are, therefore, important factors.
Read moreWhat is the mechanism of microwave heating?
Microwave heating effects work by four major mechanisms, namely dipolar polarization (rotation of dipoles), ionic conduction (ionic polarization), electronic polarization (atomic polarization), and interfacial polarization (surface polarization) as shown in Fig. 6.
Read moreWhen was the microwave oven invented?
The first commercial microwave oven was tested in a Boston restaurant in 1947 . Later that year, Raytheon introduced the Radarange 1161. It stood 5.5 feet (1.7 meters) tall, weighed 750 lbs.5 Oca 2017
