If the source of light used in a Young's double slit experiment is changed from red to violet :
Solution
According to Young's double slit experiment, the distance of nth bright fringe from the centre,<br/><br/>${y_n} = {{n\lambda D} \over d}$<br/><br/>Since, ${\lambda _{violet}} < {\lambda _{red}}$<br/><br/>$\therefore$ ${y_{violet}} < {y_{red}}$<br/><br/>$\therefore$ Consecutive fringe lines will come closer.
