Transmission refers to the process of electromagnetic radiation passing through a medium. When electromagnetic waves move through a material without being absorbed or reflected, we say they are transmitted. If no radiation is reflected or absorbed at all, the material achieves 100% transmission.
- When electromagnetic waves move through a material without being absorbed or reflected, we say they are transmitted.
- If no radiation is reflected or absorbed , the material achieves 100% transmission.
- Transmittance meanwhile is a way to measure how well a material allows light or other forms of radiation to be transmitted through it. It is essentially the fraction of incoming radiation that gets transmitted through the material.
- A high transmittance value indicates the material allows most radiation to pass through, while a low transmittance indicates most radiation is absorbed or reflected.
