SUMMARY

The discussion focuses on calculating the shortest wavelength photon emitted during electron transitions in the Lyman, Balmer, and Paschen series of the hydrogen atom. Participants clarify that the electron can start from any energy level, with the highest energy level being n=infinity, which corresponds to a free electron. The formula for determining the maximum energy (E-max) for hydrogen is provided as E-max = ((2.18*10^-18)/(6.63*10^-34)) * ((1/n)-(1/m)), where n is the initial energy level and m is the final energy level, with n greater than m.

PREREQUISITES
  • Understanding of quantum mechanics and electron transitions
  • Familiarity with the hydrogen atom energy levels
  • Knowledge of the Lyman, Balmer, and Paschen series
  • Basic proficiency in using the formula for energy transitions in hydrogen
NEXT STEPS
  • Research the derivation of the Rydberg formula for hydrogen transitions

Homework Statement



4. (a) Find the shortest wavelength photon emitted by a downward electron transition in the
Lyman, Balmer, and Paschen series of the hydrogen atom.

My only question is, what energy state is the electron starting from? is it n=infinity? or is there some part of this I am missing?
 
Physics news on Phys.org
Electrons can start from any energy level and end up in any energy level. Which transition would give the greatest frequency?
 
well the higher the starting energy level, the shorter the wavelength, so i would assume n=infinity,

so what's n=infinity for hydrogen?
 
It means a free electron in rest, very far away from the nucleus, so no force acting on it.

I have the same problem, I need to find "E-max" for hydrogen. I know that I should take ((2.18*10^-18)/(6.63*10^-34)) * ((1/n)-(1/m)) (Where n>m)
