Chapter 18, Problem 18.55E
Interpretation Introduction

(a)

Interpretation:

The equivalent force constant is to be calculated.

Concept introduction:

The Hook’s law states that the strain produced in a solid is directly proportional to the applied force on it. The classical harmonic oscillator shows repetitive motion. It follows the Hook’s law. The Hook’s law is given by,

F=Kx

Where,

F is the force.

K is the spring constant.

x is the deformation.

Interpretation Introduction

(b)

Interpretation:

The wavenumber of the light is to be calculated.

Concept introduction:

The relation between wavenumber and frequency is given by the formula,

ν=cv¯

Where,

c is the speed of light.

v¯ is the wavenumber.

ν is the frequency.

Interpretation Introduction

(c)

Interpretation:

Whether the answer of part b agrees with the generality that many solid materials are very good absorbers of low-energy infrared light is to be stated.

Concept introduction:

The relation between wavenumber and frequency is given by the formula,

ν=cv¯

Where,

c is the speed of light.

v¯ is the wavenumber.

ν is the frequency.

The relation between wavenumber and energy is given by the formula,

E=hcv¯

Where,

h is the planck’s constant.
