(i)
Interpretation:
The depth at which intensity of light becomes half the surface intensity has to be calculated.
Concept introduction:
The relation between the absorbance of a substance with its concentration and path length is given by Beer-lambert law. It states that the transmitted intensity
The Beer-lambert law is shown below.
(ii)
Interpretation:
The depth at which the intensity of light becomes one-tenth of the surface intensity has to be calculated.
Concept introduction:
The Beer-lambert law states that the transmitted intensity
The Beer-lambert law is shown below.
