Chapter 5.3, Problem 5.4E

(a)

Interpretation Introduction

Interpretation:

From the given wavelength of lines, the colour of each line has to be identified.

(b)

Interpretation Introduction

Interpretation:

The energy of photon corresponding to each line has to be calculated.

Concept Introduction:

The energy of light is given by,

    $\begin{array}{l}\text{E}\text{=}\text{hν}\\ \\ \text{E}\text{is}\text{energy}\text{of}\text{photon}\\ \\ \text{h}\text{is planck's constant}\\ \\ \text{ν}\text{is}\text{frequency}\text{of}\text{light}\text{.}\end{array}$
