What is electromagnetic radiation and where does it come from?

Electromagnetic radiation is made when an atom absorbs energy. The absorbed energy causes one or more electrons to change their locale within the atom. When the electron returns to its original position, an electromagnetic wave is produced.

Where are electromagnetic radiation from?

Electromagnetic radiation is produced whenever a charged particle, such as an electron, changes its velocity—i.e., whenever it is accelerated or decelerated. The energy of the electromagnetic radiation thus produced comes from the charged particle and is therefore lost by it.

What is electromagnetic radiation in simple words?

In layman’s terms electromagnetic radiation is light that travels by oscillating in waves at a constant speed carrying energy. … In layman’s terms, light travels by oscillating in waves at a constant speed carrying energy – interactions with objects vary depending on the energy these waves carry.

What is electromagnetic radiation and examples?

Radio waves, microwaves, visible light, and x rays are all examples of electromagnetic waves that differ from each other in wavelength. … These waves are also called “electromagnetic radiation” because they radiate from the electrically charged particles.

Is electromagnetic radiation harmful?

Despite extensive research, to date there is no evidence to conclude that exposure to low level electromagnetic fields is harmful to human health. The focus of international research is the investigation of possible links between cancer and electromagnetic fields, at power line and radiofrequencies.

What is the process of electromagnetic radiation?

Electromagnetic radiation is made when an atom absorbs energy. The absorbed energy causes one or more electrons to change their locale within the atom. When the electron returns to its original position, an electromagnetic wave is produced.

What is the other term for electromagnetic radiation?

It comes from natural and man-made sources. Electromagnetic radiation can vary in strength from low energy to high energy. It includes radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays. Also called EMR.

Who discovered electromagnetic radiation?

About 150 years ago, James Clerk Maxwell, an English scientist, developed a scientific theory to explain electromagnetic waves.

What is the difference between electromagnetic radiation and electromagnetic waves?

What is the difference between electromagnetic waves and electromagnetic radiation? The terms electromagnetic radiation and electromagnetic waves all refer to the same physical phenomenon: electromagnetic energy. This energy is described by frequency, wavelength, or energy.

What are 5 examples of electromagnetic radiation?

They include:

  • Radio Waves.
  • TV waves.
  • Radar waves.
  • Heat (infrared radiation)
  • Light.
  • Ultraviolet Light (This is what causes Sunburns)
  • X-rays (Just like the kind you get at the doctor’s office)
  • Short waves.

What are the diseases caused by electromagnetic radiation?

This review summarizes the evidence stating that excessive exposure to magnetic fields from power lines and other sources of electric current increases the risk of development of some cancers and neurodegenerative diseases, and that excessive exposure to RF radiation increases risk of cancer, male infertility, and …

How far away should you sleep from an electrical panel?

Is it dangerous to sleep near an electrical panel? No, but you should try to sleep at least 1 m (3.3 ft) away from it. Since electrical panels give off radiation, sleeping next to them isn’t recommended. Over time, the radiation can build up in your system, leading to symptoms like fatigue, headaches, and mood swings.

How does electromagnetic radiation affect the brain?

It has been found that RF-EMF can induce changes in central nervous system nerve cells, including neuronal cell apoptosis, changes in the function of the nerve myelin and ion channels; furthermore, RF-EMF act as a stress source in living creatures.
