WebConsequently, the pressure on the black side is larger than the pressure on the white side. So there is a net force that pushes from black to white. The radiometer will move from left to right. It explains why the radiometer does not work in a total vacuum. The air moves in a direction and by Newton’s third law in the radiometer. WebAnswer (1 of 4): You’ve seen this little device. It looks like a lightbulb with a weather vane inside it. Hold it up to a light source, and the weather vane spins.

WebThe Crookes radiometer wouldn’t be such a big deal, but no one, not even the scientists, knows exactly what makes it work. Clearly, it has something to do with the sun and the color contrast of the metal surfaces. Then there are the gas molecules. When the bulb is evacuated to a high vacuum, the vane no longer rotates.
