Chapter 20, Problem 20.35QP

Interpretation Introduction

Interpretation:

The impact of increase in population on greenhouse effect has to be discussed.

Concept Introduction:

Greenhouse effect:

Earth receives solar energy from sun, which is in range of wavelength between $\text{100 and 5000nm}$ but only most radiations are in $\text{400-700nm}$(visible region).  On the other hand, earth surface emits radiation of wavelength greater than $\text{4000nm}$(IR region).  These outgoing IR radiations are trapped near surface of earth by IR active compounds. Thus glass roof of greenhouse only allows visible light and absorbs IR radiations.  This effect is called as greenhouse effect.
