The allowed energies of a quantum system are 1.0 ev, 2.0 ev, 4.0 ev, and 7.0 ev. what wavelengths appear in the system's emission spectrum

The possible wavelengths that appear in the emission spectrum of the system are .

Further Explanation:

Given:

The quantum energy levels allowed in the system are:

Concept:

As the transition of electron takes from one energy level to another, there is an emission of particular wavelength from the transition. The relation between the wavelength of the emission and the energy of the energy level is expressed as:

Here,  is the final energy level,  is the initial energy level and  is the wavelength of emission.

(1). Transition of electron from  to  energy level:

(2). Transition of electron from  to  energy level:

(3). Transition of electron from  to  energy level:

(4). Transition of electron from  to  energy level:

(5). Transition of electron from  to   energy level:

(6). Transition of electron from   to   energy level:

Thus, The possible wavelengths that appear in the emission spectrum of the system are .
