• 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.
