Sol. Let m base th bright fringe of violet light overlaps with n base th bright fringe of red light. ∴ m * 400nm * D/d = n * 700nm * D/d ⇒ m/n = 7/4 ⇒ 7 base th bright fringe of violet light overlaps with 4 base th bright fringe of red light (minimum). Also, it can be seen that 14 base th violet fringe will overlap 8 base th red fringe. Because, m/n = 7/4 = 14/8.
