A water baffle 220 is installed inside the side wall of the demonstration tank 110 where the micro water pump 210 is installed. The water baffle 220 is used to block the splash of water from the outlet of the micro water pump 210. The atomization mechanism includes an isolation shell 310 installed on the other side of the demonstration tank 110, and a water baffle 220 provided at the bottom of the inner cavity of the isolation shell 310. An ultrasonic nebulizer 320, a controller 330 fixedly installed on the outside of the demonstration tank 110 and connected to the ultrasonic nebulizer 320 by wires, a fan 340 arranged on the top of the inner cavity of the isolation shell 310, and a wind nozzle 350 installed on the outside of the top of the isolation shell 310 and facing the fan 340.

[0023] Specifically, a water storage tank 240 is used to store water, and a micro water pump 210 is used to extract water, thereby ensuring that the water level inside the demonstration tank 110 is always maintained at the center of the index plate 130, avoiding the water level being too low or too high, which would cause errors in the reading of the index plate 130, thereby improving the accuracy of the device;

In addition, the rotatable inner rotating ring 150 and the outer rotating ring 180 are provided so that the underwater laser emitter 170 and the surface laser emitter 190 can adjust the incident angle, thereby improving the flexibility of use of the device.

[0025] The working principle and usage process of the present invention are as follows: first, place the device on the table, then connect the power supply to start the device, use the micro water pump 210 to extract the water source in the water storage tank 240 and inject it into the demonstration tank 110 until the water level reaches the center of the index plate 130, stop injecting water, then start the ultrasonic atomizer 320 and the fan 340 to atomize the water and spray it into the demonstration tank 110, and then select the corresponding operation mode according to the current teaching content;

[0026] 1. Demonstrate the refraction of light in air: Start the underwater laser transmitter 190 and install the mounting plate 134 in the middle of the indexing plate 130. Use the reflection of the double-sided reflector 135 to study the refraction of light in air.

[0027] Second, to demonstrate the refraction of light in water, the underwater laser transmitter 170 is activated to illuminate the double-sided reflector 135 for refraction;

[0028] The following demonstration can be performed by removing the double-sided reflector 135:

[0029] 3. Study the change in the refraction angle of light from air into water. Start the underwater laser transmitter 190 to illuminate the center of the index plate 130. Observe the change in the angle of light and read the scale on the index plate 130 to obtain the change in the refraction angle from air into water. Also, rotate the underwater laser transmitter 190 along the index plate 130 to adjust the incident angle and record further angle changes.

[0030] 4. Demonstrate the change in the refraction angle of light from water to air and the phenomenon of total internal reflection. Start the underwater laser transmitter 170 and control the angle of the underwater laser transmitter 170 using the control handle 160. As the angle between the light emitted by the underwater laser transmitter 170 and the water surface gradually decreases until the angle reaches 48.5 degrees, the light is totally reflected in the water.

[0031] After the final demonstration is completed, drain the water, keep it dry and store it.
