Transmittance - Meaning, Definition & English Examples
Transmittance is the measure of how much light or other radiation passes through a material, expressed as the ratio of transmitted to incident energy. It is commonly used in optics and spectroscopy.
Definition:
The fraction of incident light or energy that passes through a medium.
Synonyms:
transmission, permeability, conductance, passage
Part of Speech:
noun
Antonyms:
opacity, blockage, absorption
Common Collocations:
high transmittance, low transmittance, light transmittance, thermal transmittance
Derivatives:
transmit, transmitter, transmissible
Usage Tips:
Use "transmittance" when discussing light or energy passing through materials like glass or air.
Common Phrases:
"transmittance spectrum, " "optical transmittance, " "UV transmittance"
Etymology:
Derived from Latin "transmittere," meaning "to send across."
Examples:
- 1. The glass has high transmittance for visible light.
- 2. Scientists measured the transmittance of the new solar panel coating.
- 3. Low transmittance in this filter blocks harmful UV rays.
- 4. The material's thermal transmittance affects its insulation properties.
