There is no doubt that the tremendous development that took place in the countries of the world led to an interest in everything that saves time and effort, which is why man has always resorted to investigating and inventing everything that would provide him with comfort and a decent life. Like all women want it to facilitate the process of heating food.
microwave
A microwave is an electrical device that uses microwaves to heat and cook food. The electrical energy flowing in the conductor is converted into microwave energy, and microwaves are electromagnetic waves of a certain frequency. Microbeams are used for many uses, such as transmitting information from one point to another to reach the television.
Discover the microwave
The microwave radiation on which the microwave depends was discovered by the engineer Spencer in 1946, when he was carrying out some experiments with the magnetron -a vacuum tube-. He noticed that the chocolate in his pocket had melted and concluded that he had been exposed to heat until it melted that way. He put wheat next to the magnetron and noticed that it turned into popcorn, then he brought an egg and placed it next to the magnetron and noticed that it was subjected to great pressure which caused it to explode, so he concluded that the magnetron produces lightning that affect
He started by making a box and made a small hole in it that allowed the microwave rays to pass through and retained the heat and prevented it from escaping. .
The microwave is dangerous
The principle of heating food in a microwave is based on the fact that the radiation evaporates the water molecules that are between the atoms of the food, thus providing thermal energy that heats the food. Normally, there is no danger from microwaves, since the internal walls prevent these rays from escaping.
But when there is any change in the order of movement of the rays inside the microwave, it can become dangerous, as this energy is ionized due to the presence of a piece of metal inside the microwave after it is turned on, since there is a kind of wall between this body and the oven door in the form of ionized air, such as that produced by Thunder cloud, and this air is a conductor of electric current.
The danger of radiation also lies in the fact that it produces a very high voltage, which is fatal if someone is exposed to it. Some Russian experiments also indicated that continuous exposure to these rays can cause diseases such as cancer in the long term.
