About the Double Slit Experiment
This visualization focuses on wave propagation in the double slit experiment. When light passes through narrow slits, it behaves as a wave, creating an interference pattern.
In this simulation, you can see:
- Wave propagation from each slit (semi-circular wavefronts)
- Interference patterns where waves meet (bright areas show constructive interference, dark areas show destructive interference)
- Intensity pattern at the top of the screen showing what would be observed on a detector
Try changing the parameters to see how they affect the interference pattern:
- Number of Slits: More slits create sharper, more complex patterns
- Slit Width: Wider slits produce less pronounced diffraction effects
- Slit Separation: Greater separation creates narrower fringes
- Wavelength: Longer wavelengths create wider fringes
