Calorimetric Estimation of strength pf copper

 1QWhat is transmittance

Transmittance (T) is the fraction of incident light which is transmitted. In other words, it's the amount of light that “successfully” passes through the substance and comes out the other side. It is defined as T = I/Io, where I = transmitted light (“output”) and Io = incident light (“input”).

2Q What is absorbance

Absorbance (A), also known as optical density (OD), is the quantity of light absorbed by a solution.

3Q State beer Lamberts law

The Beer-Lambert law states that there is a linear relationship between the concentration and the absorbance of the solution, which enables the concentration of a solution to be calculated by measuring its absorbance.

A = Ecl

A            Absorbance

                        E        molar absorbance coefficient

              C             molar concentration

    l     optical path length

4QWhat is the shape of the graph between absorbance and concentration.
