Refraction at a convergent lens / at a divergent lens

Benefits

• Reflection-free basin on adjustable feet
• Amplitude and frequency variable excitation dipper system
• Stroboscope for synchronous and "slow-motion" projection of waves
• Simultaneous LED display of: frequency, amplitude, phase shift and type of illumination
• Control of all parameters takes place via the keypad located on top
• Projection on transparent drwaing table for distortion-free image of the wave pattern
• Green LED for brilliant pictures
• A simple display of the wave pattern is easily possible by placement of a sheet of paper
