Quantum Tunneling Lab
Compare particle energy with a barrier and see how transmission changes across classically forbidden space.
Open simulation Explore barrier penetration →Physics Simulations
Small interactive labs for big physical ideas
A growing set of browser-based simulations inspired by hands-on physics exploration. Each page is original, lightweight, and designed to run cleanly on GitHub Pages.
What is here now
Start with the quantum labs, then move into mechanics, gravity, and waves. More topic pages can be added one by one in the same format.
Quantum

Atomic Spectra Lab
Jump between hydrogen energy levels and estimate the photon color or ultraviolet line produced.
Open simulation Inspect quantum transitions →Quantum
Double-Slit Lab
Adjust wavelength and slit spacing to see how interference fringes tighten, spread, and brighten.
Open simulation Watch fringes form →Quantum
Quantum Oscillator Lab
Move through harmonic oscillator levels and compare each energy state with its probability profile.
Open simulation Inspect bound states →Quantum
Photoelectric Effect Lab
Change light frequency and intensity to see when electrons are emitted and how energetic they become.
Open simulation Test Einstein's rule →Quantum
Quantum Well Lab
Switch between bound states in a 1D box and compare how wavelength, energy, and nodes scale together.
