YOUNG'S DOUBLE SLIT EXPERIMENT :=

This exoeriment was performed by young.it tells us that the light and matter both can display charcteristics of both clasiccally defined waves and particles..

young performed this experiment using light,and gives us wave theory of light.that light exihibit dual characteristics one of particle nature and other is wave nature..

the experiment is reffered to dual path experiment,where a wave coming from source splits into two different wave. then combine constructively or destructively depending upon the phase to create interference pattern.so,young postulated that LIGHT is a wave subjected to superposition principle.The ratio of wavelength of light to the spacing of slits i.e ( Λ/d) must be smaller than 1, to obtain seprate interference fringes.so, he was able to determine the wavelength of light.

so, young double slit experiment also helps to calculate the wavelength of light used.
