Chapter 5, Problem 109CP

Interpretation Introduction

Interpretation: The observation of the coloured lines by the scientists in the spectra of heated atoms should be explained.

Concept Introduction: The arrangement of different types of electromagnetic radiation from shortest to longest wavelength is known as electromagnetic spectrum.

The wave equation is as follows:

  $E=\frac{hc}{\lambda }$

According to the above equation, wavelength is inversely proportional to the frequency. Thus, if wavelength decreases frequency increases. According to the scientists, energy of electromagnetic radiation is proportional to the frequency and inversely proportional to wavelength.
