Question: Two lasers are shining on a double slit, with slit separation d. Laser 1 has a wavelength of d/20, whereas laser 2 has a wavelength of d/15. The lasers produce separate interference patterns on a screen a distance 4.60 m away from the slits.
Part A Which laser has its first maximum closer to the central maximum?
Part B What is the distance Î"ymaxâˆ'max between the first maxima (on the same side of the central maximum) of the two patterns?
Part C What is the distance Î"ymaxâˆ'min between the second maximum of laser 1 and the third minimum of laser 2, on the same side of the central maximum?
