🌈 The Physics of Diffraction: Slits, Gratings, and Patterns
See how light bends, spreads, and forms brilliant fringes — step by step.
When light passes through a narrow slit or a diffraction grating, it doesn’t behave “straight-line simple” anymore. This focused course guides you through single-slit diffraction, double-slit interference, and diffraction gratings using clear visuals, intuitive explanations, and worked examples.
- 🌊 Understand diffraction as wave spreading (when gap size ≈ wavelength)
- 🔬 Explain single- and double-slit patterns (maxima, minima, fringe spacing)
- 📐 Use diffraction equations to calculate wavelength and slit/grating spacing
- 🌈 Connect diffraction gratings to real spectroscopy & modern tech
