Artificial rubies have an atomic system consisting of three main energy levels and can be used to produce short pulses of laser light. The energies of these levels are Eo, E1 and E2, in increasing order of energy (a) Write down an expression giving the relative population of the energy levels Eo and E1 at thermal equilibrium. b) Explain what is meant by the term population inversion. Described how this is achieved in a three-level laser system Photons of wavelength...

An imaginary atom has just three energy levels 0 eV, 1 eV, and 3 eV. Draw an energy level diagram for this atom, and show all possible transitions between these energy levels. For each transition, determine the photon energy and the photon wavelength. Which transitions involve the emission or absorption of visible light?

3. Atomic physics of sodium. In the sodium atom, there is a transition between the 3s and 3p atomic states that produces the yellow-orange light seen in many street lamps a. Sodium has 11 protons and 11 electrons with ten of the electrons filling the n =1 and n = 2 levels. Including interactions between the outer electron and the electrons in the underlying shells, should the 3s or the 3p energy level have the highest energy? Use properties of...

A certain type of atom
(not hydrogen) has three energy levels numbered 1, 2, and
3, as shown in the upper illustration. There are three possible
transitions between these levels that lead to emission of a photon:
3 ® 1, 3 ® 2, and 2 ® 1.
The lower illustration shows the emission spectrum from a gas of
these atoms. There are three emission lines, A, B, and C.
(a) Rank the photons emitted in the transitions 3 ®...
