Day 365: Free Particle - Time-Independent Schrödinger Equation

Day 365 of 2,016~12 min read

Learning Objectives

  • •**Derive the time-independent Schrödinger equation** for a free particle (V=0)
  • •**Solve the TISE** to obtain plane wave solutions
  • •**Interpret the dispersion relation** E = ℏ²k²/2m physically
  • •**Explain why the spectrum is continuous** rather than discrete
  • •**Distinguish traveling waves from standing waves** in the free particle context
  • •**Visualize plane waves** and understand their physical meaning
