Electromagnetic Waves Properties

Electromagnetic Waves Properties: This article has been told about Electromagnetic Waves Properties. Hope the students will get help from this article.
So let us know what are Electromagnetic Waves Properties?

Electromagnetic Waves

  • No medium is require for the propagation of electromagnetic waves.
  • These waves can also propagate in a vacuum.
  • These waves are transverse waves arising from the oscillations of magnetic and electric fields, e.g. light waves, thermal radiation, X rays, radio waves, etc.
  • The wavelength of these waves is very wide.
  • Their range is 10-14 m. to 104 m. Happens till.


Waves are mainly divided into two parts:

  • Machanical Waves
  • Non- Machanical Waves

(i) Mechanical Waves: Waves that propagate in a material medium (solid, liquid, or gas) calls mechanical waves.

(ii) Mechanical wave or electromagnetic wave: Waves that do not require any medium for propagation, that is, waves can also propagate in a vacuum, which calls electromagnetic or non-mechanical waves.

Electromagnetic Waves Properties

  • There is no charge on these waves, that is, they are neutral waves.
  • These waves have both momentum and energy.
  • The speed of electromagnetic waves is equal to the speed of light
  • Electromagnetic waves exert pressure on the surface they strike
  • Electromagnetic waves propagate or travel with the speed of light.
  • In these waves, the electric field, the magnetic field and the transmission vector, all lie perpendicular to each other.
  • The concept of these waves was first presented by Maxwell, so we can say that electromagnetic waves were discovered by Maxwell.
  • These are transverse waves, that is, the oscillations of these waves are perpendicular to the direction of propagation.

Major Electromagnetic Waves :-

Visible Radiation 

Inventor: Newton
Wavelength Range: 3.9 x 10^-7m to 7.8 x10^-7m
Frequency Range Hz:10^14 to 10^12
Usage: It allows us to see objects.

Important Points For Electromagnetic Waves:

  • Its existence is due to the oscillation of electric field and magnetic field.
  • Its speed in other mediums is less than its speed in zero.
  • It is a transverse wave.
  • In this, the electric field and the magnetic field oscillate perpendicularly to each other.
  • The speed of light in zero or vacuum is about 3 lakh km/s which is a constant. No object can accelerate faster than this.
  • The part of the electromagnetic radiation that the human eye is sensitive to is called visible light.
  • The wavelength of visible light ranges from 4000 angstroms to 8000 angstroms.
  • Both electricity and magnetism are electromagnetic effects.
  • Electromagnetic radiation also has energy and momentum. When these waves react with a substance, they provide energy and momentum to the molecules (atoms or electrons) of the substance.
