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

• University level
• Constructive = bright yellow, destructive = dark
• Use parametric curves for circular waves
