The discussion revolves around the double slit experiment, specifically focusing on the effects of using white light instead of monochromatic light. The original poster seeks clarification on why the central fringe appears white while colored fringes appear on either side, questioning if this is due to the different angles of deviation for each color caused by diffraction at the slits.
The conversation includes attempts to clarify the reasoning behind the observed phenomena, with some participants affirming the original poster's understanding. However, there is no explicit consensus on the explanation provided, and the discussion remains open to further exploration.
Participants reference a textbook for explanations, indicating that the discussion is framed within the constraints of textbook definitions and interpretations of the double slit experiment.
Chi Meson said:Since you have a book, notice how it explains what causes there to be a "bright fringe." It has to do with the "extra distance" traveled by the light form one of the slits. How much does this extra distance have to be to create a bright fringe? Then, anwser this: different colors of light have different ____________ .
