What are the 7 electromagnetic waves and their uses?


What are the 7 electromagnetic waves and their uses?

The electromagnetic 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) light, X-rays and gamma-rays.

How are electromagnetic waves used 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 is the most useful electromagnetic wave?

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.

What are the benefits of electromagnetic waves?

These include nerve regeneration, wound healing, graft behavior, diabetes, and myocardial and cerebral ischemia (heart attack and stroke), among other conditions. Preliminary data even suggest possible benefits in controlling malignancy.

What are some 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.

What are the benefits of electromagnetic waves to humans and the society?

What is the importance of electromagnetic waves in the 21st century?

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 and refracted to change their direction. These properties make them ideal for communications.

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.

What are the beneficial of electromagnetic waves?

EMR has very beneficial uses of our daily life to make it more comfortable and easier. Nowadays, we can talk to anyone on a mobile phone through the Internet: it is because of EMR, since these waves can transmit signals for very long distanc- es. So EMR has the key roles in making our lives more comfortable.

What is the importance of electromagnetic waves in our daily Endeavours?

Electromagnetic energy has a very important role in everyday life. It can be seen from the field of technology, information, communication and in the field of health. Example in the field of communication can be seen with the use of mobile phones among the community.
