Bohr Model Simulation for A-Level Physics

Use this free Bohr model simulation to explore hydrogen energy levels, photon transitions, emission spectra and ionisation. It supports AQA, Edexcel and OCR A-Level Physics revision.

Try these investigations

• Compare transitions between different levels.
• Calculate photon energy from wavelength.
• Explain why the spectrum is discrete.

Continue with A-Level Physics questions by topic, past papers or all Physics simulations.
