Crookes radiometer - Wikipedia

The Crookes radiometer (also known as a light mill) consists of an airtight glass bulb containing a partial vacuum, with a set of vanes which are mounted on a spindle inside.The vanes rotate when exposed to light, with faster rotation for more intense light, providing a quantitative measurement of electromagnetic radiation intensity.. The reason for the rotation was a cause

Crookes Radiometer - How Does This Kids Toy Work?

It is sometimes called a light mill. Crookes radiometer appears to be a cross between a scientific invention and a child’s toy. The atmosphere inside the bulb is a modest rather than a complete vacuum, so resistance to vane rotation is minimal. It rotates as if the sun somehow pushes the black surfaces. Crookes Radiometer – Why a Big Deal?

The radiometer is more sensitive to the light of the flame, which is of a lower frequency than the LED light. The black side absorbs more light than the white one. It gets hotter, so the air temperature is larger than the temperature on the white side. Everybody knows that a white car is cooler than a black one.

How does a Crookes' radiometer work? | HowStuffWorks

Apr 01, 2000 · A Crookes' radiometer has four vanes suspended inside a glass bulb. Inside the bulb, there is a good vacuum. When you shine a light on the vanes in the radiometer, they spin -- in bright sunlight, they can spin at several thousand rotations per minute!. The vacuum is important to the radiometer's success. If there is no vacuum (that is, if the bulb is full of air),
