Presently, a number of visualization methods of sound waves are investigated in order to understand their behaviors in various mediums. In this study, we employ the visualization method using photoelasticity. In this method, the stress in elastic plates is visualized using the birefringence effect arising from ultrasound stress, through two orthogonal polarization plates. As visualization objects, we observed Lamb and Lamb-type waves under some conditions. Among them, the condition that the layer changes during the wave propagation is very interesting. Under this condition, not only Lamb and Lamb-type waves but also a propagating wave along the boundary appears at the same time. In this study, we can observe the mode conversion of elastic waves by changing the boundary condition during the wave propagation.
