The formula to calculate the Percent Transmittance (T) from Absorbance (A) is:
\[ T = 10^{(2 - A)} \]
Where:
Converting an absorbance to transmittance involves taking the antilog of 2 minus the absorbance.
Consider an example where:
Using the formula to calculate the Percent Transmittance:
\[ T = 10^{(2 - 0.5)} = 10^{1.5} \approx 31.62\% \]
This means that the percent transmittance for this example is approximately 31.62%.
