Answer:
2πc/w
Explanation:
To find the wavelength you take into account the difference in energy of two adjacent states n+1 and n:
(1)
hbar = h/2π
this energy is also the energy of an emitted photon in the transition, that is:
(2)
you equal the equations (1) and (2) and compute the wavelength:

hence, the wavelength of the emitted photon is 2πc/w
The theory of punctuated equilibrium states that is a species appear in a fossil record, they will become stable over time and can show little changes in evolution as time goes by. An example would be the feline creatures. Although cats and tigers have a different structure in their body, the facial structure and the way they hunt are similar.
