If a guided Lamb wave leaks energy from a plate into a surrounding fluid, the radiated almost plane wave has a frequency dependent angle towards the boundary. This radia- tion angle can be calculated by numerical determination of the plates' phase velocities. We also measured the radiation angle in Schlieren photographs and found a mentionable discrepancy to the calculated angles in certain frequency regions. A first approach by modifying the boundary condition could not re- solve the observed discrepancies, but a reinterpretation of the Schlieren photographs as interference patterns of different Leaky Lamb waves leads to a good correspondence between measured and calculated values.
