Chapter 8, Problem 8C.7P

Interpretation Introduction

Interpretation:

The information obtained from the closely spaced emission lines at $\text{766}\text{.70}\text{nm}$ and $\text{770}\text{.11}\text{nm}$ for potassium atoms has to be stated.

Concept introduction:

The electronic spectra are formed by the excitation and relaxation process of electrons.  The spectrum formed by an element has discrete discontinuous lines at specific wavelengths.  The discrete lines are formed because the electronic energy levels of an atom are quantized.  The electronic spectrum of an element is specific for every element.
