The results of an experimental study on the lowest wave mode of Faraday gravity waves arising on the free surface of a liquid under vertical oscillations of a container are presented. Resonance dependencies, wave profiles, wave steepness, and the formation of a planar jet were investigated. The experiments were conducted in a rectangular container with variable liquid depth, using high-speed imaging and data processing in the ImageJ software. It was shown that an increase in liquid depth changes the slope of the resonance curves, which is associated with nonlinear effects. Transitions from regular waves to jet splashes, accompanied by the formation of a planar jet and intense splashing, were recorded. The experimental results confirmed the theoretical models of Faraday parametric resonance and revealed important characteristics of wave interactions with the sidewalls of the container, which are of practical relevance for engineering applications.
