Photoelectric effect
E=hν; E_kmax=hν−W₀; eU₀=E_kmax; cutoff ν₀=W₀/h; slope of U₀–ν gives h/e.

Photoelectric effect
Photoelectric effect: photon energy exceeds work function. This “Photoelectric effect” page is an MVP interactive sketch — formulas, controls, and live readouts in the browser; a fuller bench may follow.
Photoelectric effect: photon energy exceeds work function.
Key formulas
E_k=h\nu-Wh\nu_0=WeU_c=E_k
How to use
- Adjust parameters in the left panel.
- Use play / pause and speed controls.
- Match right-side readouts to the formulas.
- Reset to return to the initial state.
Applications

- Classroom focus: cutoff ν₀=W₀/h.
FAQ
What does MVP mean on this page?
An interactive sketch with formulas and parameters. Polished Ready labs are the full bench experience.
What does the “Photoelectric effect” lab practice?
Tune parameters and match readouts to the “Photoelectric effect” relations — useful for prep and demos.
What does the photoelectric effect show?
Light has particle aspects: photon energy hν and a cutoff frequency.
Is half-life a single nucleus’s lifetime?
No — it is statistical for a large sample; one nucleus decays randomly.
