Chapter 15, Problem 15.60E

Interpretation Introduction

Interpretation:

An explanation corresponding to the fact that it is impossible to emit blue light from a transition that absorbs red light initially is to be stated.

Concept introduction:

When the transition of an electron occurs from a higher level of energy to a lower level, a single photon is emitted for each dropping electron.

The energy of a photon of light is calculated by the formula shown below.

$E=\frac{hc}{\lambda }$

The energy of a photon of light is directly proportional to its wavelength.
