A laser with wavelength d/8d/8 is shining light on a double slit with slit separation 0.500 mmmm . This results in an interference pattern on a screen a distance LLL away from the slits. We wish to shine a second laser, with a different wavelength, through the same slits
What is the wavelength (λ2) of the second laser that would place its second maximum at the same location as the fourth minimum of the first laser when a laser with wavelength λ = d/8 is shining light on a double slit with slit separation d = 0.500 mm and a screen is located at a distance L away from the slits?
A) λ2 = 4λ.
B) λ2 = λ/4.
C) λ2 = 8λ.
D) λ2 = λ/8.
