Mixture of lights consiosting of wavele...

Mixture of lights consiosting of wavelengths 590 nm and an unknown wavelength illuminates young' s double slit and gives rise to two overlapping interference patterns on the screen . The central maximum of both lights coincide. Further, it is observed that the third brright fringe of 590 m light conincides with the fourth bright fringe of the other light. From this data, calculate the unknown wave length.
