Double-Slit Diffraction Simulation for A-Level Physics

Use this free double-slit simulation to explore interference, path difference, phase and fringe spacing. It supports AQA, Edexcel and OCR A-Level Physics revision.

Try these investigations

• Find points of constructive interference.
• Find points of destructive interference.
• Predict the effect of changing wavelength.
