Interference Patterns when using red light and blue light The diagrams below are not to scale. They represent the interference patterns observed when using i) red light (l
= about 650nm) and
ii) blue light (l = about 450nm)
The fringe spacing is smaller for the blue light than for the red light, as predicted by the theory.
