MVP — interactive sketch; a fuller lab is coming later.

Single-slit diffraction

Fraunhofer single-slit I=I₀(sinβ/β)², β=πa·sinθ/λ; dark fringes a·sinθ=mλ; central bright is widest.

Single-slit diffraction

Single slit diffraction pattern. This “Single-slit diffraction” page is an MVP interactive sketch — formulas, controls, and live readouts in the browser; a fuller bench may follow.

Single slit diffraction pattern.

How to use

  1. Adjust parameters in the left panel.
  2. Use play / pause and speed controls.
  3. Match right-side readouts to the formulas.
  4. Reset to return to the initial state.

Applications

  • Single-slit diffraction: Single slit diffraction pattern.
  • Classroom focus: dark fringes a·sinθ=mλ.

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.
