Geometric Ray Optics

Drag the object arrow to visualize focal tracing and real vs. virtual image formation.

Optical Element:

Focal Length (f):

80 px

Object Height (h):

50 px

Object Distance (u): -

Image Distance (v): -

Magnification (m): -

Image Type: -

Thin Lens Formula 1/f = 1/v - 1/u [Lens sign conventions apply]

Mirror Formula 1/f = 1/v + 1/u [Mirror sign conventions apply]

Young's Double Slit Experiment

Adjust wave parameters to observe bright/dark interference fringes and real-time intensity mappings.

Wavelength (λ):

550 nm

Slit Separation (d):

0.25 mm

Distance to Screen (D):

2.0 m

Fringe Width (β): -

Central Maxima position: Y = 0 mm

Pattern Status: Coherent Fringes

Fringe Width (β) β = λ · D / d

Intensity Distribution (I) I = 4 · I₀ · cos²(π · d · y / (λ · D))
