CAN YOU PLEASE HELP ME WITH THE FOLLOWING PROBLEM

Problem 2: Thin Films To the right is a density experiment that we are going to use as a zoomed in thin film experiment. no = 1.00 (a) For each layer here tell me if the light reflected off the layer would be inverted or not inverted. n, = 1.40 How do you know? Lamp Oil .so Rubbing Alochol .87 n2 = 1.33 (b) A thin film is made out of layers 2-4, what would the minimum thickness be of layer 3 if green light n3 = 1.48 Vegi oil . FI () = 500nm) constructively interfered? Water 1.00 n = 1.33 (c) What would be the thickness if you used the ns = 1.43 same light but made the thin film with layers Dawn Dish Soap 1.03 3-5? n6 = 1.47 Karo Syrup 1.33 (d) Compare your two thicknesses. Do they make n7 = 1.60 sense? Why do they do/do not make sense? Honey 1.34 ng = 1.52
