Double Slit Experiment Simulation
Wave interference creates bright/dark patterns
Light passing through two slits creates an interference pattern on the screen — bright and dark bands from constructive and destructive interference.
What Is Double Slit Experiment?
A conceptual visualization of interference from two coherent wave sources (the slits). The screen intensity depends on the path difference between contributions from each slit.
What To Observe
- Bright fringes appear where phase alignment is constructive.
- Dark regions appear where the two contributions cancel.
- Changing slit separation and wavelength reshapes fringe spacing.
