Why microwave is called microwave?

Answer 1

Most people would think that microwaves use heat to warm up the food, but that isn't true. As you know almost every food has traces of water. What a microwave does is it send waves of electricity which "excites" the water inside the food. When water is "Excited" it produces heat which warms up the food. So basically the food warms it's self up. For example have you seen when lightining strikes a tree?. The tree sets on fire because the lightining " Excites " the water in the tree. So then the tree produces heat and sets it self on fire because it produced too much

Hope this helped

Answer 2

The microwaves are generally described as electromagnetic waves with frequencies that range about 300MHz to 300GHz. Because of their high frequencies, have relatively short wavelengths, hence the name is "micro"waves (wavelength= speed of light/frequency) which is speed of light=3x108.

Answer 3

A microwave oven is called a 'microwave' because that is the type of radio wave it uses to induce heat. An RF wave with a frequency between 300 MHz and 300 GHz is considered a microwave. Microwave ovens typically operate around 1-2 GHz.

It is always surprising as to why they are called micro waves when their frequency is in Giga range.

Its because, their wavelength is in micron range.

Answer 4

The beauty of microwaves is amazing. It uses radiation and convection(some) to heat up the substance you are heating. I recommend not going near the microwave as it is doing its heating process, too much radiation= not a healthy person

Answer 5

Complex answer. Simply put, electrons are accelerated through a magnetic field. This causes them to run in a spiral course, where they meet a ring of resonant cavities' As the electron velocity is modulated by the cavity E fields, they bunch and excite the cavities.

Answer 6

It creates micro-waves (a long-wavelength low frequency elctro-magnetic wave very similar to radio waves). Those waves vibrate water molecules in the food you are cooking. The friction of the vibration creates heat which cooks your food. The need of water molecules to produce heat is why glass plates and anhydrous plastics can be used to cook food without melting--they don't contain water. Plastics that do contain water will melt into your food in the microwave.

Answer 7

there were made to help people reheat food and not turn on the stove and have to wait on it to heat up or burn and plus on the microwave you can put in the minutes you want it at

Answer 8

Their name describes their wavelengths on the order of millimetres or micrometres.
