The geometric resonance has been predicted in a periodically corrugated waveguide. It is shown that for a change in thickness of the waveguide, at some of its value, one of the cut-off frequencies would split into two, separated by the forbidden gap, while other cut-off frequencies experience only slight shifts due to the periodicity. The resonant splitting forms the single spectral line in the forbidden gap of the electromagnetic spectrum of the waveguide.
