| Abstract: | Based on the intensity distribution of monochromatic light source, this paper ex-plores the effect of light source dimension and spectnim width on the visibility of interfer-ence fringe under common circumstances and the author offers the example of Young'sTwo Split Interference to reach the conclusion that the visibility of interference fringe va-ries with light source demension and spectnim width according to the regularity of sincfunction. |
