ConcepTest <strong>24</strong>.7d Two identical microscopic slides in air illuminated with light from a laser are creating an interference pattern. The space between the slides is now filled with water (n=1.33( =1.33). What happens to the interference fringes? Parallel Slides IV 1) Spaced farther apart 2) Spaced closer together 3) No change The path difference between ray #2 and ray #3 is 2t (in addition, ray #3 experiences a phase change of 180°). Thus, the dark fringes will occur for: 2t = m mλ water n where λ = λ water air / Thus, the water has decreased the wavelength of the light. ray 1 ray 2 ray 3 t
