How Do Electron Wavelengths Compare in Different Transitions?

Click For Summary
SUMMARY

The discussion centers on calculating the wavelength of a photon emitted when an electron transitions from the third energy level to the lowest energy level in a quantum box of width 0.1 nm. Participants emphasize using the infinite-square well energy formula to determine the emitted energy and subsequently applying the photon energy formula to find the wavelength. Additionally, the Bohr energy equation is recommended for comparing this wavelength with that of a transition from the third energy level to the ground state in hydrogen, where the ground state energy is 13.6 eV.

PREREQUISITES
  • Understanding of quantum mechanics concepts, specifically the infinite-square well model.
  • Familiarity with the Bohr model of the hydrogen atom.
  • Knowledge of photon energy calculations using the formula E = hc/λ.
  • Basic algebra skills for manipulating equations and solving for wavelength.
NEXT STEPS
  • Study the infinite-square well energy formula and its applications in quantum mechanics.
  • Learn how to apply the Bohr energy equation to calculate energy levels in hydrogen.
  • Research the relationship between energy transitions and photon wavelength calculations.
  • Explore practical examples of quantum transitions in different atomic systems.
USEFUL FOR

Students preparing for exams in quantum mechanics, physics educators, and anyone interested in the principles of electron transitions and photon emissions.

Homework Statement


An electron makes a transition from the third energy level to the lowest energy level in a box of width 0.1 nm. what is the wavelength of the emitted photon? Compare this wavelength with the wavelength associated with the transition from the third energy level to the ground state level in hyrdogen. (The ground state energy of hydrogen is 13.6 eV. )


Homework Equations





The Attempt at a Solution


I am really lost. And this is one of the review questions for the test coming up.
Can anyone please get me started or at least point me in the right direction?
I would REALLY aprreciate it!
Thanks!

How is the energy of the nth level related to the width of the box?
 
You should use the energy formula for the infinite-square well to obtain energy emitted, then I think you can use this energy in the formula of the photon and get the wavelength. Bohr energy equation can be used to find the energy for the hydrogen atom.
