WebWhile the mathematics of thin film interference can become quite complicated, it is clear from this discussion that thin film interference is another phenomenon that can only be explained using a wave model of light. Next Section: … WebChange of stress in a thin film on the surface of a cantilever is illustrated in Fig. 6.33. On the left, the cantilever bends downward and expands until the stress created in the cantilever balances the expanding film on top. The stress on the top side of the supporting cantilever is tensile, because it is pulled by the film.
