Thin Film Interference Simulation
Reflected color varies with film thickness and angle
What Is Thin Film Interference?
Thin Film Interference refers to reflected color varies with film thickness and angle in optics & light. This page visualizes the phenomenon with interactive controls so you can change parameters and observe how the model responds.
What To Observe
- Watch how the visual pattern or system response changes as you adjust the controls for Thin Film Interference.
- Relate each visual change to the core phenomenon shown here: reflected color varies with film thickness and angle.
- Use repeated runs with one parameter changed at a time to build intuition.
