**Concept introduction:**

The percent transmittance of a solution is the ability of the solution to allow the monochromatic light to pass through it. The percent transmittance of a solution is the ratio of the intensity of monochromatic light incident on the solution to the intensity transmitted through the solution.

The relation between the absorbance and transmittance is established by the Beer’s law.
