Chapter 1, Problem 1.28E

(a)

Interpretation Introduction

Interpretation:

Wavelength of the light emitted by the nanowire has to be calculated.

Concept Introduction:

Wavelength and frequency are inversely proportional to each other and the relationship between wavelength and frequency can be given as,

  $\text{ν}\text{=}\frac{\text{c}}{\text{λ}}$

Here, $\text{ν}$ is the frequency, $\text{λ}$ is the wavelength and c is the speed of light

(b)

Interpretation Introduction

Interpretation:

Frequency of the light from the second wire has to be calculated.

Concept Introduction:

Refer to (a).
