Meaning
The fraction of radiant energy that passes through a substance.
Classification
Nouns denoting quantities and units of measure.
Examples
- The spectrophotometer measured the transmittance of light through the transparent sample to determine its chemical composition.
- When analyzing the substance, the scientists noted a significant decrease in transmittance due to the addition of opaque particles.
- In materials science, a high transmittance is often desirable for applications such as solar panels and optical fibers.
- The transmittance of the glass window was affected by the presence of imperfections and impurities in the material.
- Researchers used the transmittance data to calculate the absorption coefficient of the substance and understand its optical properties.
