Question

Difference between double slit and single slit experiment

Answer 1

double slit : slit which is twice or double

single slit : slit which is single in number

Answer 2

in a single silt diffraction;light spread out in a line perpendicular to the silt . No perticular interesting phenomena are observed. But in a double slit diffraction, light diffracts when passing though the slits, but the light waves coming out from those slits interfere with each other to produce an interference pattern on the screen. The light is spread out in a line, like in the single slit, but here there is interference, producing regions of constructive (bright fringes) and destructive (dark fringes) interference and a very bright spot at the centre of the screen, called the central maxima.
