Chapter 8, Problem 105IAE

Interpretation Introduction

Interpretation:

The velocity of the two recoiling chlorine atoms which absorbed 300 nm wavelength photons should be calculated.

Concept introduction:

Energy of a photon is given by

$E=h\nu$

E = energy of a photon

h = plank constant

ν = frequency

If there is some excess energy of an atom after absorbing a photon, the energy turns into kinetic energy, and then the velocity of that atom can be determined by following equation.

$\begin{array}{l}{E}_{Kinetic}=\frac{1}{2}m{v}^2\\ \text{Where,}\\ E_{Kinetic}\text{= Kinetic energy }\\ m=\text{mass }\\ v=\text{velocity}\end{array}$
