In the wave tank the depth of the water is 9 mm. The velocity of propagation depends on the thickness of the fluid layer. Let us place in the tank a 6 mm tick glass plate. Above the glass plate the velociyt of wave propagation will be different which will also be shown by the change of wavelength. The change in he direction of propagation will follow the Snellius-Descartes law.
