Product Introduction
The ripple tank physical equipmentt is a special teaching experimental instrument for the teaching demonstration experiment of "mechanical wave" in middle school physics. It uses the projection of water waves to display various wave forms and physical phenomena such as wave formation, propagation, reflection, interference, diffraction and reflection. By adjusting the vibration frequency, the images of dynamic waveform and static waveform can be displayed on the screen of the instrument. The instrument adopts a lifting light source structure, which is easy to use and intuitive to demonstrate. In particular, the use of high-efficiency LED energy-saving light source and electronic stroboscopic technology has greatly improved the safety and service life of the instrument.

Experimental operation
1) Demonstrate a circular wave
Fix the single vibrator on the vibrating plate, turn on the power switch, and the instrument will enter the working state. By vibrating up and down the vibrator, a circular wave image will appear on the screen.
Adjust the vibration frequency knob according to the experimental needs. When the vibration frequency is the same as the light source frequency, the water wave is in a static state on the screen; when the vibration frequency is greater than the light source frequency, the water wave is in a diffuse state on the screen; when the vibration frequency is less than the light source frequency, the water wave is in a state of diffusion. It is in a contracted state on the screen; if the projection of the water wave is not clear, the amplitude screw can be adjusted until it is clear.
2) Demonstrate the diffraction of waves
After adjusting the circular wave according to the above method, place the two baffles in a line about 20mm from the center of the vibrator. The distance between the two baffles is close to the wavelength, and a significant diffraction phenomenon can be seen. distance, different diffraction phenomena can be seen.
3) Demonstration of two-vibrator interference waves
Fix the double vibrator and adjust it according to the above method to see the obvious interference wave image.
4) Demonstrate plane waves
Fix the flat vibrator and adjust it according to the above method, so that the lower edge of the vibrator is parallel to the horizontal plane, and the intersection should be fully moistened, otherwise the image will be slightly curved.
5) Demonstrate the reflection of waves
Place the straight baffle at a 45° angle in front of the plane wave, that is, to see the image of the plane reflected wave. By adjusting the angle of the baffle, you can see different reflected images.
Product feature and application
Used for the visual demonstration of the properties of wave motion and the effects of refraction, diffraction and interference.
1. Frequency can be adjusted
2. The height of the light source pole is adjustable
3. LED light source has a long service life
Maintenance and precautions
1. Do not fill the water tank too much, so as not to overflow and damage the internal circuit.
2. After the instrument is used, pour out the water and let it dry, loosen the locking screw of the connecting rod, put down the movable connecting rod, cover the dust cover or put it back in the box.
3. The instrument should be placed in a cool, dry place without corrosive gas, and avoid heavy pressure and collision.
