🌈 Wave Optics: Diffraction Simulator
Wave OpticsWhat's happening? Diffraction: light bends around obstacles. d·sinθ = nλ gives minima positions. Narrower slit = wider diffraction pattern. This is how diffraction gratings work!
Wave Optics is a core concept tested across JEE Main and Advanced.
Understanding this concept visually builds the intuition you need to solve numerical problems faster and avoid common mistakes.

Step-by-step
How to approach Wave Optics problems
- Identify the variables — list what's given and what's asked.
- Apply the core formula — d·sinθ = nλ.
- Check units — convert to SI units before calculating.
- Verify with intuition — does the answer make physical sense?
