Two point sources emit circular waves — where they meet, you see constructive and destructive interference fringes. Drag either source on the canvas to reposition it and watch the pattern update live.

Governing equation

y = A_{1} sin (k r_{1} - ω t) + A_{2} sin (k r_{2} - ω t), Δ r = mλ, λ \approx 15.7 px, Δ s = 100 px

Reading this result: Wavelength is about 15.7 px and the two sources sit 100 px apart. Bright fringes appear where the path difference to the two sources equals a whole number of wavelengths (constructive interference); dark fringes fall halfway between, where the difference is a half-wavelength (destructive interference). Shrinking the wavelength or widening the separation would pack more fringes into the same space.

The iconic experiment: two slits create interference fringes, modulated by each slit's diffraction envelope.

Regimeinterference-dominated

Governing equation

I = I_{0} cos^{2} \frac{π d sin θ}{λ} sinc^{2} \frac{π a sin θ}{λ}, Δ y = \frac{λ L}{d} = \frac{20 \cdot 800}{40} = 400

Reading this result: Two-slit interference sets the fine fringe spacing (∝ λ/d) while single-slit diffraction sets the envelope (∝ λ/a); here about 10 bright fringes fit under the central peak.

Slit width (µm)

Wavelength (nm)

Send light through a narrow slit and it fans out into a bright central band flanked by dimmer fringes — diffraction. The pattern follows a sinc-squared curve, with the first dark fringe where the path difference across the slit equals one wavelength. Narrower slits spread the light more, the diffraction limit that caps every lens and telescope's sharpness.

Slit/λ36.4

Governing equation

I = I_{0} sinc^{2} β, β = \frac{π a sin θ}{λ}, a = 20 μ m, λ = 550 nm

Reading this result: Wide slit relative to the wavelength: the central peak is tight and the beam stays nearly collimated, with only faint fringes.
