In a Young's double slit experiment with slit separation 0.1 mm, one observes a bright fringe at angle `(1)/(40)` rad by using light of wavelength `lamda_(1).` When the light of wavelength `lamda_(2)` is used a bright fringe is seen at the same at the same angle in the same set up. Given that `lamda_(1) and lamda_(2)` are in visible range (380 nm to 740 nm), their values are :
