In Young's double slit experiment, red light of wavelength of `6000Å` is used and the `n^(th)` bright fringe is obtained at a ponit P on the screen. Keeping the same setting, the source of light is replaced by green light of wavelength `5000Å` and now `(n+1)^(th)` bright fringe is obtained at the point P on the screen. The value of `n` is
