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?
