Chapter 20, Problem 20.11QP

Interpretation Introduction

Interpretation:

The wavelength of a photon required to dissociate $\text{OH}$ bond has to be calculated from the given bond enthalpy.

Concept Introduction:

The mathematical equation of various characteristics of light wave is

$\text{c = νλ}$

C is the speed of light ($\text{3}{\text{.00 × 10}}^{\text{8}}\text{ m/s}$).

$\text{ν}$ is the frequency

$\text{λ}$ is wavelength.

$\text{E}\text{=}\text{hν}$

h is Planck’s constant ($\text{6}\text{.63}\text{×}{\text{10}}^{\text{-34}}\text{J}\text{.s}$ ) which relates energy and frequency.

$\text{ν}$ is the frequency.

E is the energy of light particle
