sci.wave-interference-double-slit Calculator
Calculates double-slit interference fringe spacing and intensity distribution: I(θ) = I₀ cos²(πd sin θ/λ). Young's double-slit experiment (1801) first demonstrated light's wave nature — with d = 0.5 mm and L = 2 m at λ = 500 nm, fringes are 2 mm apart.
Inputs
Wavelength Nm
Distance between successive wave crests. Related to frequency: λ = speed / frequency.
Slit Separation Mm
Reference formula or conversion factor shown for context.
Screen Distance M
Separation between two points or total path length. Check that units are consistent throughout the calculation.
Fringe Order
Reference formula or conversion factor shown for context.
