Wave Interference & Double Slit
受眾: University類別: Physics
簡介
Two point sources emit circular waves. Where waves meet in phase, constructive interference produces bright bands; out of phase produces dark bands. A double-slit diffraction pattern is shown on a screen. The condition for maxima d·sinθ = mλ is displayed.

Wave Interference & Double Slit
Description
Two point sources emit circular waves. Where waves meet in phase, constructive interference produces bright bands; out of phase produces dark bands. A double-slit diffraction pattern is shown on a screen. The condition for maxima d·sinθ = mλ is displayed.
Phases
| # | Phase Name | Duration | Description |
|---|---|---|---|
| 1 | Two Sources | 3s | Circular waves from two sources expand |
| 2 | Interference Pattern | 3s | Bright/dark interference bands highlighted |
| 3 | Double Slit Setup | 3s | Slit barrier and screen appear |
| 4 | Diffraction Pattern | 3s | Intensity pattern on screen drawn |
| 5 | Formula | 2s | d·sinθ = mλ for maxima |
