Experimental optical and acoustic study of cavitation bubble collapse near solid wall in water was performed. The bubble was generated by discharge of low-voltage capacitor into a couple of wires closing a simple circuit. Three different distances from the solid wall were studied. The bubble radius was studied using time-resolved photography and by PVDF hydrophone submerged in the glass bath representing the solid wall. The impact power was estimated from the time-resolved photography of the bubble jet and from the hydrophone signal.
