Schrodinger equation and hydrogen atom

Click For Summary
SUMMARY

The discussion focuses on determining the width L of a one-dimensional box where the n=5 energy level corresponds to the absolute value of the n=3 state of a hydrogen atom. Participants confirm the use of the equation n²h²/8mL², with n=5, to equate it to the energy of the n=3 state of hydrogen, which is -13.6 eV divided by 32. The importance of omitting signs and ensuring the absolute values are equal is emphasized, alongside the necessity of converting electron volts to joules for accurate calculations.

PREREQUISITES
  • Understanding of quantum mechanics principles, specifically the Schrödinger equation.
  • Familiarity with the energy levels of the hydrogen atom.
  • Knowledge of the relationship between energy, wavelength, and mass in quantum systems.
  • Ability to convert energy units from electron volts (eV) to joules (J).
NEXT STEPS
  • Study the derivation and applications of the Schrödinger equation in quantum mechanics.
  • Learn about the energy level calculations for hydrogen atoms and their significance.
  • Explore the concept of one-dimensional quantum wells and their properties.
  • Investigate unit conversions between electron volts and joules in physics problems.
USEFUL FOR

Students and educators in physics, particularly those studying quantum mechanics and atomic structure, as well as anyone involved in solving quantum energy level problems.

Homework Statement


Find the width L of a one-dimensional box for which n=5 level would correspond to the absolute value of the n=3 state of a hydrogen atom


Homework Equations


am i suppose to use n2h2/8mL2 where n=5 to equate it to the n=3 state of the hydrogen atom? which is -13.6eV/32?


The Attempt at a Solution



i am confuse. or am i suppose to be using some other equations? i don't really understand the question though. appreciate any help

You have to use these equations. Omit the signs, the absolute values have to be equal. m is the mass of the electron, and convert eV to joule.
