In Young's double slit experiment, how many maximas can be obtained on a screen (including the central maximum) on both sides of the central fringe if lambda = 2000 Å and d = 7000 Å? |

Answer» 12 or `sin theta = (n lambda)/(d) = (n(2000))/(7000) = (n)/(3.5)` As , `sin theta le 1` `therefore n = 0, 1, 2, 3, `only. THUS only seven max.can be seen on both sides if the SCREEN. |
