How does a Crookes radiometer work? | …
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 ...
Radiometer - Wikipedia
A radiometer or roentgenometer is a device for measuring the radiant flux (power) of electromagnetic radiation. Generally, a radiometer is an infrared radiation detector or an ultraviolet detector. Microwave radiometers operate in the microwave wavelengths. While the term radiometer can refer to any device that measures electromagnetic radiation (e.g. light), the term is often used to refer specifically to a Crookes radiometer("light-mill"), a device invented in 1873 in …
