Chapter 7, Problem 7.20QE
Interpretation Introduction

Interpretation:

The frequency and spectral region of the light emitted by an excited atom of lead has to be determined.

Concept Introduction:

The wave nature of any light can be described by its frequency, wavelength, and amplitude. The wavelength (λ, lambda) of the light is defined as the distance between two successive peaks. Its SI unit is meter. The frequency (v) is defined as the number of waves that can pass through the one point in 1 second. Its SI unit is s1. The amplitude (A) of the light wave is the maximum height of a wave.

The relation between frequency (v) and wavelength (λ) of the light is as follows:

  v=cλ        (1)

Here, c is the speed of light and its value is 3.00×108 m/s.
