Electromagnetic waves : The wave which are produced when a particle is accelerated due to varying electric and magnetic field. EMW consist both electric and magnetic field perpendicular to each other as well as perpendicular to the direction of propagation of wave.
Properties of Electromagnetic waves are ---
- They do not require any medium to travel.
- When these waves are arranged from low wavelength to high wavelength region, then they forms a spectrum known as EM spectrum.
- Gamma waves are the lowest wavelength wave and radio waves are the highest wavelength wave of EM spectrum.
- EM waves shows all the characteristics of wave like frequency, amplitude, wavelength etc.
- These waves follows the relation ---
f = 1/T and
c = f入
{c=speed of light, f=frequency, 入=wavelength }
