Interpretation Introduction

Interpretation:

In a spectrophotometer, the origin of shot noise needs to be described. The variation in the relative uncertainty with concentration needs to be explained if short noise is the major noise source.

Concept introduction:

The term noise in analytical chemistry refers to the collection of all sources of unwanted signals from the particular instrument. So noise related to spectrophotometry is the collection of interfering signals occurs during a measurement.

Relative concentration uncertainty is,

Relative concentration uncertainty = Absolute uncertainty of concentrationCalculated concentration
