A double slit interference pattern is producedby a parallel beam of light passing through two slits .of unequal width20 lamda and 40 lamda respectively where lamda is the wave length of the light used.the distance between the center of the slit is 1000 lamda if the fringes are observed on a screen far off from the slit D>>1000 lamda calculate theseparation of two adjecent maxima
