Answer» unchanged Finally WIDHT of ringe `barx_(2)=(lambda_(2)D_(2))/(2d_(2))` where `d_(2)=(d_(1))/(2),D_(2)=2D_(1) and lambda_(1)=lambda_(2)` `:. barx_(2)=(lambda_(1)(2D_(1)))/(2((d_(1))/(2)))=(4lambda_(1)D_(1))/(2d_(1))""...(2)` TAKING ratio of EQUATION (2) and (1) `(barx_(2))/(x_(1))=(4lambda_(1)D_(1))/(2d_(1))xx(2d_(1))/(lambda_(1)D_(1))` `:.barx_(2)=4barx_(1)` |
