In double-slit interference, when m=2, it indicates that one wave travels two wavelengths longer than the other wave from the opposite slit, resulting in a bright fringe. This phenomenon occurs due to the differing path lengths of the waves as they emerge at an angle from the slits. The longer path length leads to constructive interference, which is essential for understanding the formation of bright fringes in interference patterns.

Yes, that's exactly what it means.lha08 said:Homework Statement
I was just wondering in double-slit interference, when it's a bright fringe, let's say m=2, does that mean that one wave coming from one of the slits is traveling 2 wavelengths longer than than the other wavelength coming from the other slit?
It works because the waves coming out of the slit travel at some angle, so that one of the paths is longer. See the figure here:How does that work?
Thanks
