About this item

Product name: Hair wave sink Size: 330*280mm*40mm/12.99*11.02*1.57 in Material: organic glass + electronic components Weight: about 800g Demonstration of water wave interference: 1. Put the instrument on the projector and pour cold water into the sink (raw water is also acceptable, but it is prone to bubbles), the water depth is about 1cm. 2. Turn on the switch of the projector, touch the water with your finger, adjust the lens, so that the water waves form a ripple image with greater contrast on the screen. 3. Clamp the vibration source seat in the middle of the side of the sink, make the dual vibrators face down, and just touch the water at the same time, then tighten the knob. 4. Install the No. 1 battery in the battery card, insert the motor plug into the differential mother, adjust the potentiometer to make the eccentric wheel rotate, the starting frequency is higher, slowly adjust the low frequency (about 7Hz), and at the same time adjust the focal length of the projector appropriately. Until the clear water wave interference fringes appeared on the screen. 5. Cut off the power after the demonstration.
