WebI learned the thin lens equation as 1/f = (1/di) + (1/do). Khan academy is stating that it is 1/f = (1/di) - (1/do). Which one is it? I am struggling so bad on when to know if the image … WebA thin film is one having a thickness t smaller than a few times the wavelength of light, λ. Since color is associated indirectly with λ and because all interference depends in some way on the ratio of λ to the size of the object involved, we should expect to see different colors for different thicknesses of a film, as in Figure 3.11.
