Physics Final Year Topic: Uncertainty in Planck-Constant Estimates from Permitted Photoelectric-Effect Records

This Physics final year project reanalyses stopping-potential observations with explicit calibration and fitting assumptions.

Generate the Complete Project Read project brief

Why choose this project topic?

A focused study of photoelectric data gives you a specific question in quantum measurement. It reanalyses stopping-potential observations with explicit calibration and fitting assumptions. The bounded comparison creates room to explain how your evidence supports an interpretation and where the method has limits.

How do frequency calibration and regression choices affect a Planck-constant estimate from a photoelectric dataset?

Agree the apparatus or dataset, comparison range and feasible measurement schedule for photoelectric data with your supervisor.

Proposed project objectives

  1. 01Define the materials, variables and comparison conditions for photoelectric data.
  2. 02Use authorised measurements with documented apparatus and wavelength information.
  3. 03Evaluate the measurements or model outputs in relation to this question: How do frequency calibration and regression choices affect a Planck-constant estimate from a photoelectric dataset?

A suggested research approach

Use authorised measurements with documented apparatus and wavelength information. Inspect calibration and uncertainty, compare defensible line-fitting methods and report intercept interpretation separately from the slope estimate. Agree the available resources and record uncertainty, deviations from the protocol and any observations that challenge the initial interpretation.

What you will need

  • Permitted photoelectric-effect measurements
  • Wavelength and voltage calibration metadata
  • Software for uncertainty-aware regression

Keep your project scope clear

Reanalysis of a small teaching dataset is not a new precision determination of a fundamental constant.
