In Young's double-slit experiment with slit separation 0.1 m, one observes a bright fringe at angle 1/40 rad by using the light of wavelength λ1. When the light of wavelength λ2 is used a bright fringe is seen at the same angle in the same setup. Given that λ1 and λ2 are in the visible range (380 nm to 740 nm), their values are
