What are three examples of electromagnetic waves being used?
When you listen to the radio, watch TV, or cook dinner in a microwave oven, you are using electromagnetic waves. Radio waves, television waves, and microwaves are all types of electromagnetic waves. They only differ from each other in wavelength. Wavelength is the distance between one wave crest to the next.
What are the uses of electromagnetic waves in the development of engineering?
Harnessing the electromagnetic waves has created a revolution in engineering applications, with great impacts on various fields such as communication systems, industrial/biomedical sensing, remote sensing, radar, medical imaging and treatment, appliances, security screening, and so on.
What is the importance of waves in our lives?
These waves have many uses which are vital to our daily lives: visible light allows us to see; microwaves and radio waves allow for long-range communication via mobile phones, television and radio; infra-red waves are used in night-vision cameras and in many remote controls; and x-rays are used in medical imaging; and …
What household items 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.
How do we use electromagnetic waves in our everyday lives?
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.
How do we use electromagnetic waves in everyday life?

What are facts about electromagnetic waves?
The electromagnetic spectrum is the complete range of electromagnetic waves on a continuous distribution from a very low range of frequencies and energy levels, with a correspondingly long wavelength, to a very high range of frequencies and energy levels, with a correspondingly short wavelength.
What are some examples of EM waves?
Examples of electromagnetic energy include gamma rays, X-rays, ultraviolet radiation, visible light and infrared radiation, as well as microwaves and radio waves. Electromagnetic energy is any self-propagating energy that has an electric and a magnetic field.
What is an example of electromagnetic spectrum?
Electromagnetic energy comes in many examples including gamma rays, X-rays, ultraviolet radiation, visible light, microwaves, radio waves and infrared radiation. The electromagnetic spectrum is the range of all types of electromagnetic radiation (electromagnetic radiation being a type of electromagnetic energy).
