Transmittance
—
The probe is outside the beam or the light is off.
A = εbc and T = 10⁻ᴬ. Doubling concentration or path length doubles absorbance; transmittance does not decrease linearly.
Model notes
- Monochromatic light passes through a uniform solution according to Beer–Lambert law within the source concentration ranges. Absorptivity depends on solution and wavelength. The chart shows ε/εₘₐₓ, normalized to the maximum of each substance.
- The probe must cover the full beam width to measure. Inside the cuvette, optical path length ends at the probe.
- Artwork color and brightness support observation; read A and %T for quantities. This static model does not model photon travel time.
