Chapter 7, Problem 31E

Interpretation Introduction

Interpretation:

The type of light that damages the biological molecules is to be identified and the reason behind this is to be defined.

Concept Introduction:

The distance between two consecutive crests of a wave is called wavelength.

The group of ions or atoms that are present in a living organism is called a biological molecule.

A small packet of energy associated with light (electromagnetic radiation) is called photon.

The relation between energy of a photon and wavelength is as follows:

${{\rm E}}_{\text{photon}}\propto \frac{1}{\lambda }$

Here, ${{\rm E}}_{\text{photon}}$ is the photon energy and $\lambda$ is the wavelength of light.
