Transmission

Transmission takes place when light (electromagnetic radiation) passes through a medium.

  • Transmission refers to the passage of any form of electromagnetic radiation through a medium.
  • If no light is reflected or absorbed as light travels through a medium, then the light achieves 100% transmission.
  • The term transmittance of a material refers to its effectiveness in transmitting radiant energy. It is the fraction of incident electromagnetic power that is transmitted through the material.
