Chapter 18, Problem 18.7P

Interpretation Introduction

Interpretation:

Reason behind red color transmittance by blue-green color when the wavelength of $\text{480 nm}$ is absorbed to a maximum extent has to be given.

Concept Introduction:

Expression to compute absorbance as per Beer’s law is as follows:

  $A=\epsilon \cdot b\cdot c$

Expression to compute transmittance from absorbance is as follows:

  $T={10}^{-A}$

Here,

$\epsilon$ denotes molar absorptivity of species capable to absorb.

$b$ denotes path length in centimeters.

$c$ denotes the concentration of species capable to absorb

$A$ denotes absorbance.

$T$ denotes transmittance.
