What Is Electromagnetic Energy and Why Is It Important?

Last Updated on February 15, 2024 by Nasir Hanif

What do you know about electromagnetic energy? Do you know how it affects your daily life? We’re going to what it is and why it’s important you know this information.

Since electronic devices are integrated into society, electromagnetic fields are being generated with them. Research shows these waves are unintentionally absorbed by human and animal bodies. Although the research is unclear, concerns are rising about the possible biological effects.

You’ll discover there are seven types of this energy. Some are good, but you should limit the others.

Keep reading to learn more about electromagnetic energy.

What Is Electromagnetic Energy

Electromagnetic energy, EM radiation, and electromagnetism are terms for various energies. These wavelengths travel through space at the speed of light. Each wavelength’s measured on the electromagnetic spectrum and contains individual properties.

Electromagnetic energy’s one of the four forces of nature. Each force has different strength levels and varying ranges.

What’s the Electromagnetic Spectrum

The electromagnetic spectrum is a series of electromagnetic radiation wavelengths. The wavelengths range from long to short. The spectrum covers all seven electromagnetic types.

Combining observations at different wavelengths, the spectrum completes a picture of an object’s structure, composition, and behavior.

Electromagnetic Types

Each electromagnetic type has its frequency and wavelength. The longer the wavelength, the lower the frequency. The following are the seven types of electromagnetic energies measured from the longest wavelengths to shortest:

  • Radio waves
  • Microwaves
  • Infrared radiation
  • Visible light
  • Ultraviolet radiation (UV)
  • X-rays
  • Gamma rays

The frequencies are measured in Hertz (Hz), megahertz (MHz), and gigahertz (GHz). The higher the frequency, the more electromagnetic energy the wavelength is transporting.

How They Work

Radio waves use an antenna to vibrate at a certain frequency and generate a specific electromagnetic wavelength for cars, GPS positioning, broadcasting, wireless networks, cell phone networks, and more. Microwaves are primarily used in radar and microwave ovens. Infrared radiation (IR) is invisible to the human eye, but NASA uses it in machinery to detect faraway stars, and fields of gas or dust.

The sun emits visible light, and the eye detects colors from it. The sun also emits ultraviolet radiation that can damage skin, DNA, and cause cancer. X-rays and gamma rays are sources of radiation that cause cancer and destroy biological life. These reasons are why these radiation sources are tightly controlled.

Electromagnetic Protection

With the right technology, you can discover your exposure to different electromagnetic fields. The features of the trifield emf meter offer fast and accurate measurements.

Its unique frequency weighted mode provides the extent of currents affecting the human body.
