Information on Electromagnetic Radiation and Its Characters

In electromagnetic radiation the emission and absorption of energy occur thorough charged particles. It is made up of electric and magnetic fields that oscillate at the speed of light through space. The following are some features of electromagnetic radiation:


The distance between two successive crust and truf is known as the wavelength. Wavelength can be expressed in meters or nanometers. Longer wavelength electromagnetic radiation has low energy.


The frequency is the number of oscillations per second in oscillating electric and magnetic field. Hertz (Hz) is the unit of frequency. lower frequency electromagnetic radiation has low energy.


The electric and magnetic fields’ maximum deviation from their normal location is measured by their amplitude. It controls the radiation’s brightness or intensity.


Electromagnetic radiation has constant speed in a vacuum  which is 299,792,458 metres per second (m/s).


Polarisation is referred to how electric and magnetic fields is oriented. Radiation can be polarised in one of several ways, including vertically or horizontally.


Magnetic radiation interacts with matter to transfer its energy. Electromagnetic radiation carries energy. The frequency or wavelength of radiation give information about  how much energy it can carry.


The electromagnetic spectrum includes all wavelength and frequency ranges such as

  • radio waves
  • microwaves
  • infrared radiation
  • visible light
  • ultraviolet radiation
  • X-rays, and gamma rays, among other types of electromagnetic radiation.
