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 4.50 m away from the slits. part a which laser has its first maximum closer to the central maximum?

Answer: x (1) = n Î" L / d = 1. (d / 20). 4.2 / d = 0.21 m x (2) = 4.2 / 15 = 0.28 m So distance between them is 0.07 m b) x (1) = 0.42 (for the 2nd max) x (2) = 2.5. 0.28 = 0.7 m (for the 3rd in) Separation = 0.28 m
