A laser with wavelength d/8 is shining light on a double slit with slit separation 0.450 mm. This results in an interference pattern on a screen a distance L away from the slits. We wish to shine a second laser, with a different wavelength, through the same slits. What is the wavelength ? of the second laser that would place its second maximum at the same location as the fourth minimum of the first laser, if d = 0.450 mm?
