A parallel beam of light consisting of two wavelenths lambda_1 = 4000 Å and lambda_2 = 8000 Å is incident perpendicular to plane of both slits in a typical Young’s double slit experiment. The seperation between both slits is d = 2mm and the distance between slits and screen is D = 1 meter. In each situation of column-I a point P on screen is specified by its distance ‘l’ from central bright on screen. Match the proper entries from column-2 to column-1 using the codes given below the columns {:("Column-I",,"Column-II"),((P) "At P such that l=0",,"(1) intensity is maximum for " lambda_(1)=4000Å),((Q) "At P such that l=0.1mm",,"(2) intensity is maximum for " lambda_(1)=4000Å),((R) "At P such that l=0.2mm",,"(1) intensity is maximum for " lambda_(2)=8000Å),((S) "At P such that l=0.4",,"(4) intensity is maximum for " lambda_(1)=8000Å):}
