Interference of Light
When two coherent light waves meet, they superpose. Constructive interference: path difference = nλ → bright fringe. Destructive interference: path difference = (2n+1)λ/2 → dark fringe. Coherent sources: same frequency, constant phase difference. White light: colored fringes because different λ diffract differently.
