1. DOUBLE SLIT INTERFERENCE YOUNG’S SLITS Interference pattern (“fringes”) MONOCHROMATIC LIGHT SOURCE Single slit acts as a single monochromatic source for the double slit Double Slits Beams interfere in region of overlap
2.
3. DOUBLE SLIT INTERFERENCE YOUNG’S SLITS w = the distance between adjacent fringes (fringe width) s = the distance between slits (slit width) D = distance from slits to screen Optical path distance b s This is too w D
4. DOUBLE SLIT INTERFERENCE YOUNG’S SLITS DOUBLE SLIT INTERFERENCE YOUNG’S SLITS and for small angles For a bright fringe b= (or some multiple of it) so w/D=s/ ie Optical path distance b s This is too w D
