# (a) Interpretation: The theoretical absorbance value for 345 nm should be derived and the data should be plotted. Concept introduction: The relationship between absorbance and concentration of absorbance is linear. If the incident light I o falls on the sample solutions then only I amount of light gets transmitted through the solution. And the relationship is defined as below: Absorbance(A) = I o I Transmission(T) = I I o In the case of no absorbing sample, all the light gets passed and the value of T = 100 % . But in the case of absorbing sample, the absorbance is given by A = log ( 1 T ) . ### Principles of Instrumental Analysis

Interpretation Introduction

## (a)Interpretation:The theoretical absorbance value for 345 nm should be derived and the data should be plotted.Concept introduction:The relationship between absorbance and concentration of absorbance is linear. If the incident light Io falls on the sample solutions then only I amount of light gets transmitted through the solution. And the relationship is defined as below:Absorbance(A)=IoITransmission(T)=IIoIn the case of no absorbing sample, all the light gets passed and the value of T=100%. But in the case of absorbing sample, the absorbance is given by A=log(1T).

### (b)Interpretation:The theoretical absorbance value for 370 nm should be derived and the data should be plotted.Concept introduction:The relationship between absorbance and concentration of absorbance is linear. If the incident light Io falls on the sample solutions then only I amount of light gets transmitted through the solution. And the relationship is defined as below:Absorbance(A)=IoITransmission(T)=IIoIn the case of no absorbing sample, all the light gets passed and the value of T=100%. But in the case of absorbing sample, the absorbance is given by A=log(1T).
