A microwave is a kind of electromagnetic radiation with wavelengths ranging from roughly one meter to one millimeter.
We have all used microwaves in our homes to heat food, but did you know that we use microwaves do not generate thermal energy themselves? Instead, it uses electromagnetic waves to generate heat. So curious to know what are electromagnetic waves? Read on to find out!
Electromagnetic radiation comprises the vibration of the electric and magnetic fields. These waves travel over space carrying electromagnetic radiant energy.
Microwaves carry cell phone signals over the air. By altering the frequency of the waves, a mobile phone envelops the acoustics of the caller's speech in microwaves. Frequency modulation is the technical term for this. The cellphone then sends the encapsulated microwaves over the atmosphere to a cell tower. The waves move from the cellphone tower to a switching center. They then go to a different cell tower, connected to the recipient of the person being phoned. The encoded microwaves are converted back to sounds by the receiver.
1. What are the three uses of microwaves?
Microwaves are utilized extensively in modern technologies, including point-to-point communication systems, wireless networks, and microwave radio relay networks.
2. What are microwaves waves used for?
One of the most popular uses of microwaves is to heat meals quickly. Microwave ovens are conceivable because microwaves can convey heat energy.
3. Why are microwaves so bad?
When used correctly, there’s nothing to worry about in terms of a microwave’s radiation, according to the World Health Organization. But care should be taken to not heat anything in a plastic container unless it’s labeled safe for use.
