What are some uses of electromagnetic waves?

What are the 7 electromagnetic waves and their uses?

The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.

What are 4 examples of electromagnetic waves?

Radio waves, microwaves, visible light, and x rays are all examples of electromagnetic waves that differ from each other in wavelength. (a) Longer wavelength; (b) shorter wavelength. Electromagnetic waves are produced by the motion of electrically charged particles.

How do we use electromagnetic waves in everyday life?

Everyday life is pervaded by artificially made electromagnetic radiation: food is heated in microwave ovens, airplanes are guided by radar waves, television sets receive electromagnetic waves transmitted by broadcasting stations, and infrared waves from heaters provide warmth.

What are 3 uses of radio waves?

They are used in standard broadcast radio and television, shortwave radio, navigation and air-traffic control, cellular telephony, and even remote-controlled toys. (For a fuller treatment, see electromagnetic radiation: Radio waves.)

What are five examples of electromagnetic waves?

List five examples of electromagnetic radiation. Electromagnetic radiation is a form of energy that exhibits wavelike behavior as it moves through space. Examples are: radio waves, microwaves, infrared light, visible light, ultra violet, x-rays, and gamma rays.

What are some household items that use electromagnetic waves?

Many household appliances produce electromagnetic fields: low consumption light bulbs, television and computer screens, electric radiators and even electric blankets. All of these common objects emit electric or electromagnetic fields and / or function by using them.

What are 5 uses of radio waves?

Various frequencies of radio waves are used for television and FM and AM radio broadcasts, military communications, mobile phones, ham radio, wireless computer networks, and numerous other communications applications. Most radio waves pass freely through Earth’s atmosphere.

What are 5 uses of microwaves?

Microwaves are widely used in modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication, medical diathermy and cancer treatment, remote sensing, radio astronomy, particle accelerators, spectroscopy, industrial …

How are electromagnetic microwaves used?

One of the most common uses of microwaves is to heat food quickly. Microwave ovens are possible because microwaves can be used to transmit thermal energy.
