Chapter 7, Problem 7.99QE

(a)

Interpretation Introduction

Interpretation:

The energy difference between $n$ equals to 2 and 3 levels and between $n$ equal to 34 and 33 have to be determined. Also, the energy difference between them has to be compared.

Concept Introduction:

The expression to calculate the energy difference between allowed energy levels of a hydrogen atom is as follows:

  $\Delta E=2.18\times {10}^{-18}\left(\frac{1}{n_1^2}-\frac{1}{n_2^2}\right)\text{ J}$        (1)

Here, $n_1$ and $n_2$ are the energy levels of electron and also $n_1<n_2$.

(b)

Interpretation Introduction

Interpretation:

The largest energy difference observed in the hydrogen atom has to be determined.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

The reason for the presence of a limit on energy difference has to be determined.

Concept Introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

The phenomenon that corresponds to a limit on energy difference has to be determined.

Concept Introduction:

Refer to part (a).
