FAQ
What does MVP mean on this page?
An interactive sketch with formulas and parameters. Polished Ready labs are the full bench experience.
What does the “Single-slit diffraction” lab practice?
Tune parameters and match readouts to the “Single-slit diffraction” relations — useful for prep and demos.
Real vs virtual image?
Real images can form on a screen; virtual ones cannot — view by eye along rays.
How do I remember Snell’s law?
n₁sinθ₁ = n₂sinθ₂; denser medium → smaller angle to the normal.
