WebDark Fringe: discussion In Physics, Dark Fringe is often considered an “Interference fringe” which is bright in colour, mainly formed due to light beams that are present … WebSolution. Dark and bright fringes are formed due to interference. Dark fringes are formed by destructive interference where the waves are out of the phase. Bright fringes are formed …
WebSection Summary. Young’s double slit experiment gave definitive proof of the wave character of light. An interference pattern is obtained by the superposition of light from two slits. There is constructive interference when d sin θ = mλ (for m = 0, 1, −1, 2, −2,…) d sin θ = m λ ( for m = 0, 1, − 1, 2, − 2, …), where d d is the ...
