Lights of wavelengths lambda_(1)=4500 Å, lambda_(2)=6000 Å are sent through a double slit arrangement simultaneously. Then

Light from a sources emitting two wavelengths lambda_(1) and lambda_(2) is allowed to fall on Young's double-slit apparatus after filtering one of the wavelengths. The position of interference maxima is noted. When the filter is removed both the wavelengths are incident and it is found that maximum intensity is produced where the fourth maxima occured previously. If the other wavelength if filtered, at the same location the third maxima is found. What is the raito of wavelength?
