Green light has a wavelength of 500nm. What is the minimumthickness of a soap film (suspended in air) for which this filmwill appear green?
My professor has 2d= lambda/2 d= lambda/4= 500/4= 125nm
What I am confused about is why he used 2d=lambda/2. How do I knowto use a constructive equation vs. a destructive one. lambda,2lambda, 3lambda [or] lambda/2, lambda3/2, lambda5/2.
