Chapter 12.3, Problem 12.1P

(a)

Interpretation Introduction

Interpretation:

In infrared radiation of ${\text{1715cm}}^{\text{-1}}$ or of ${\text{2800cm}}^{\text{-1}}$, which is higher in energy has to be given.

Concept Introduction:

Infrared radiation is a type of electromagnetic radiation.  The electromagnetic radiation is said to be the energy propagated through free space or a medium in the form of waves.  The radiation in infrared region is referred by wave numbers.

The wave number is said to be the number of waves per centimetre.  The units of wave number is given as

  $\text{units of wavenumber = }\frac{\text{1}}{\text{cm}}{\text{ or cm}}^{\text{-1}}$

(b)

Interpretation Introduction

Interpretation:

In Radio-frequency radiation of $\text{300MHz}$ or $\text{60MHz}$, which is higher in energy has to be given.

Concept Introduction:

Radio-frequency radiation is a type of electromagnetic radiation.  The electromagnetic radiation is said to be the energy propagated through free space or a medium in the form of waves.  The radiation in Radio-frequency region is referred by frequency.

The frequency is said to be the number of waves that pass through a given point at a given time.  The units of frequency is described in Hertz (Hz).  The units of frequency is given in seconds (s).

  ${\text{frequency = s}}^{\text{-1}}\text{ or }\frac{\text{1}}{\text{s}}$
