Chapter 5, Problem 35QRT

Interpretation Introduction

Interpretation:

The energy of the photon emitted for the transition from $\text{n= 4 to n =1}$ has to be calculated.  The region in which electromagnetic spectrum lie has to be identified.

Concept Introduction:

An atom undergoes a transition from initial state of principal quantum number ${\text{n}}_{\text{i}}$ to a state with principal quantum number ${\text{n}}_{\text{f}}$ the energy change is

    ${\text{ΔE}}_{\text{atom}}\text{=}{\text{E}}_{\text{f}}\text{-}{\text{E}}_{\text{i}}\text{=}\text{-2}\text{.179}\text{×}{\text{10}}^{\text{-18}}\text{J}\left(\frac{\text{1}}{{\text{n}}_{\text{f}}{}^{\text{2}}}\text{-}\frac{\text{1}}{{\text{n}}_{\text{i}}{}^{\text{2}}}\right)$
