About this app

DiffractLab is a tool for simulating Fraunhofer diffraction patterns on your mobile device. Explore the physics of light diffraction through single and double slit experiments with real-time intensity distribution visualization.

Features:

Single Slit Diffraction: Adjust slit width and wavelength to observe the diffraction intensity pattern. View the central maximum width and secondary maxima positions calculated in real time.

Double Slit Diffraction: Configure slit width, slit separation, and wavelength to simulate the combined diffraction-interference pattern. Analyze fringe spacing and identify missing orders.

Comparison Mode: View single slit and double slit patterns side by side with an overlay option, making it easier to understand how interference fringes fit within the diffraction envelope.

Wavelength Presets: Quickly select red (650nm), green (550nm), or blue (450nm) light, or enter any custom wavelength value.

Theory Reference: Access detailed explanations of Fraunhofer diffraction formulas, including the intensity equation I = I₀ × (sinβ/β)² × cos²α, minima conditions, and parameter descriptions.

Offline Operation: All simulations run locally on your device. No internet connection required for core functionality.
