What Is the Length of the Box Based on Photon Emission Wavelengths?

Click For Summary
SUMMARY

The discussion focuses on determining the length of a quantum box based on photon emission wavelengths of 620nm and 443nm. The relevant equation used is wavelength = (8mc²L²)/(hc(ni² - nf²), which relates the wavelength of emitted photons to the quantum transitions within the box. Participants emphasize the importance of identifying the correct transitions and suggest exploring the ratios of wavelengths to derive the box length. The problem highlights the necessity of understanding quantum mechanics principles to solve for the box's dimensions accurately.

PREREQUISITES
  • Understanding of quantum mechanics principles, specifically quantum box models.
  • Familiarity with the equation relating wavelength to quantum transitions.

Homework Statement


Imagine a box of unknown length with the only visible photons emitted have 620nm and 443nm. Identify the transitions and find the length of the box.


Homework Equations


wavelength = (8mc2L2)/(hc(ni2 - nf2)


The Attempt at a Solution


So I assume that I need to do is make a guess and find the first transition. From there find the ground state and then compare this ground state to the next transition.

From the lecture on this topic though we did not go over any problems like this so I am confused as to find the first transition.

Beware the "visible" ! You don't know if there are invisible photons, but you do know that there are no photons with a wavelength in between. Try a few transitions and see what wavelength expressions you get. Perhaps an expression for the difference between two consecutive wavelengths ?
 
Try dividing one wavelength by the other
