Name: Optical pressure windmill, thermal radiation meter
Exhibit size: 400×280×350mm
Function Coconut Description: Explore the principle and application of light pressure difference, plug in the power supply, and a light is illuminated on a small windmill. Although there is no wind, the small windmill spins quickly under the light. , the car stops turning.
Structure and experimental principle: Objects of different colors absorb light differently. White objects absorb less light energy, and black objects absorb more light energy. Based on this principle, when the light-driven windmill receives sunlight, more and more energy is concentrated on the black back of the blade, resulting in a difference in light energy between the black and white blades, which is converted into mechanical energy, thereby promoting The impeller rotates. The leaves in the radiometer are alternately composed of black and white. Light shines on the leaves, the white leaves reflect the light, and the black leaves absorb the light, thus causing a light pressure difference. The light energy is converted into mechanical energy, which drives the blade to rotate, and the strong light pressure difference is large, and the rotation speed is increased.
