Electro Magnetic Spectrum

The Electro Magnetic Spectrum contain different types of waves, some of which are visible to human eye.

Properties Of The Electro Magnetic Waves:

  • They all are transverse waves.
  • They transfer energy from one place to another.
  • They can travel through vacuum, no need of medium.
  • They all travel at 3 × 108 ms-1 in a vacuum.
  • They all travel with the same speed in air.
  • They all obey the laws of reflection and refraction.
