Quantum mechanics. Schrodinger question energy level question.

Click For Summary
SUMMARY

The discussion centers on solving a quantum mechanics problem related to energy levels, specifically addressing question B1 part 2. Participants clarify that the correct approach involves using the equation for photon energy, E_{photon} = \frac{h}{\lambda}, and relating it to the energy difference between the excited state (E_n) and the ground state (E_0). The substitution of h=p\lambda into the energy formula E=n^2h^2 / 8mL^2 is not the appropriate method for this problem.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with the concept of energy levels in quantum systems
  • Knowledge of the Planck constant (h) and its applications
  • Basic proficiency in solving equations involving wavelengths and energy
NEXT STEPS
  • Study the derivation of the energy levels in quantum mechanics
  • Learn about the relationship between photon energy and wavelength
  • Explore the implications of the Schrödinger equation in quantum systems
  • Investigate the concept of ground state and excited state energies
USEFUL FOR

Students and educators in physics, particularly those focusing on quantum mechanics and energy level calculations, will benefit from this discussion.

Hey, I'm stuck. How do you do question B1 part 2?

Do you substitute h=p[tex]\lambda[/tex] into E=n^2h^2 / 8mL^2 ?

no you use the fact that [tex]E_{photon} = \frac{h}{\lambda} = E_n - E_0[/tex] where 0 stands for the energy of the groundstate
 
Got it, thanks
