Experiments are conducted to test extant theory on the effect of uniform rotation Ω on the angle θ of conical beam wave propagation excited by a sphere vertically oscillating at frequency ω in a density stratified fluid. The nearconstant Brunt–Väisälä frequency stratification N produced in situ in a rotating cylindrical tank exhibits no effect of residual motion for the range of Froude numbers investigated. Good agreement between experiment and theory is found over the range of angles 15°<θ<65° using the “synthetic schlieren” visualization technique. In particular, the cutoff for wave propagation at ω=2Ω, below which waves do not propagate, is clearly observed.
