Ever wondered what happens when we send one photon at a time through a double slit?
We all know the famous Young’s double-slit experiment—it reveals that light behaves as both a particle and a wave, with interference patterns emerging over time.
🔬We recently developed an interactive web app to simulate single-photon double-slit interference — perfect for students, educators, and enthusiasts alike!
👉 Adjust the number of photons using a slider and watch the interference pattern emerge—from random dots to well-defined fringes.
💡 Each photon interferes with itself—but collectively, a wave-like pattern arises. This is quantum mechanics at its finest!
✅ Interactive slider to adjust photon count
✅ Real-time canvas visualization
✅ No external libraries—pure HTML, CSS, and JavaScript
✅ Easy to embed into WordPress posts or pages
We would love to see educators and students experiment with this tool! Whether you’re teaching physics or simply curious, this app brings wave-particle duality to life.
For comparison purposes, the interference patterns corresponding to photon counts of 10, 100, 1,000, and 10,000 are displayed below.
