Product name: Hair wave sink Size: 360*280mm*30mm Material: organic glass + electronic components Weight: about 1000g Instructions 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.
Features
- This product uses a projector to demonstrate wave interference, diffraction and other phenomena.
- The instrument has the characteristics of simple structure, clear phenomenon, easy operation and so on. The vibration source is driven by a DC motor with a flexible shaft, which is unique in the design of this instrument.
- The instrument should be protected from dust and scratches. When it is not used for a long time, the battery should be taken out, the water tank should be dried, and the vibration source and accessories should be placed in the component tank and stored in the box.
- After a long time of use, you can add a little instrument oil to each shaft to reduce friction.
- We attach great importance to customer experience, so you can us if you have any questions, and we will get back to you within 24 hours!
