2015 Crookes Radiometer/solar Radiometer Light Mill ...
The Solar Radiometer, also known as a light mill, consists of an airtight glass bulb, containing a partial vacuum. Inside are a set of vanes which are mounted on a spindle. The vanes rotate when exposed to light, with faster rotation for more intense light, providing a quantitative measurement of electromagnetic radiation intensity.
How does a Crookes radiometer work? | HowStuffWorks
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 radiometers success. If there is no vacuum (that is, if the bulb is full of air), the vanes do not spin because there is too much …
Radiometer (light mill) - Home Science Tools
Radiometers were invented in the mid-19th century to measure the intensity of radiant energy. The vane inside a glass bulb spins as light hits it (the rate of spinning varies with the intensity of light).
