The time-independent Schrodinger equation

Stationary states and the eigenvalue form of kinetic plus potential energy acting on ψ, the time factor of unit modulus that leaves the probability density static, continuity of psi everywhere and of its derivative wherever the potential step is finite, quantization forced by boundary conditions, and the non-relativistic single-particle fixed-potential scope.

Scope & orientation

What this subsection covers

Stationary states and the eigenvalue form of kinetic plus potential energy acting on ψ, the time factor of unit modulus that leaves the probability density static, continuity of psi everywhere and of its derivative wherever the potential step is finite, quantization forced by boundary conditions,…

A strong response uses wavefunction and probability-density plots and states where the model stops being reliable.

Reasoning checklist

Evidence, assumptions and limits

01

Assumptions to state

State the system, observable, approximation, and conditions held fixed before using a model.

02

Evidence to collect

Does stopping potential vary linearly with frequency, and what value of h and work function does the fit support?

Read the complete note

Does stopping potential vary linearly with frequency, and what value of h and work function does the fit support? Useful evidence includes stopping-potential data at several source frequencies, a linear fit with slope h/e and intercept minus φ/e, residuals, propagated uncertainty, and a stated range of validity.

03

Limits to state

This GioPhysics course map is an adaptable learning sequence, not academic credit, accreditation, or a universal university syllabus. Third-semester content is the least standardised of the introductory sequence: departments place oscillations, waves, optics, and thermal physics differently, and the modern-physics units here are a bounded survey rather than a complete course in relativity, quantum mechanics, atomic, nuclear, or particle physics. Follow your institution's published scope, notation, laboratory programme, and assessment rules. A result should be checked against units, signs, limiting cases, and the conditions under which its model was derived.
