How can electromagnetic waves become useful to us?
Radio waves are used for communication such as television and radio. Radio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected to change their direction. These properties make them ideal for communications.
Which electromagnetic wave is the most useful in everyday life?
Electromagnetic waves are classified according to their frequency. The different types of waves have different uses and functions in our everyday lives. The most important of these is visible light, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves.
How does electromagnetic wave affects your life as a student?
Exposure to low frequency fields that are strong enough can lead to dizziness, seeing light flashes and feeling tingling or pain through stimulation of nerves. Exposure to radiofrequency fields that are strong enough can lead to heating of body tissue, and result in damage to tissues and organs.
What are electromagnetic waves used for in everyday life?
Electromagnetic waves are used to transmit long/short/FM wavelength radio waves, and TV/telephone/wireless signals or energies. They are also responsible for transmitting energy in the form of microwaves, infrared radiation (IR), visible light (VIS), ultraviolet light (UV), X-rays, and gamma rays.
What is the importance of waves in our lives?
They simplify our lives by letting us connect to people around the globe within second, and creating a whole “global village” that keeps the everyone in the world in touch with what is happening on the other side of them hemisphere. These waves make communication and news-spreading extremely fast and efficient.
What is the history of electromagnetic waves?
In the 1860’s and 1870’s, James Clerk Maxwell who was a scientist from Scotland was the first one to notice that if you put electric and magnetic waves together, they are very powerful- creating electromagnetic waves. Electromagnetic waves are used by cell phones, computers, televisions, and even microwaves.
