How does a crookes radiometer work

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.

WebA Crookes radiometer consists of a glass bulb from which most of the air has been removed, thereby creating a partial vacuum, and a rotor that is mounted on a vertical support inside the bulb. The rotor bears four light, horizontal arms mounted at right angles to one another on a central pivot; the rotor can turn freely in the horizontal plane.

WebInvented in 1873 by chemist & experimenter Sir William Crookes, the solar radiometer was the first way in which man could demonstrate light as an energy source. The radiometer consists of an airtight glass bulb, containing a partial vacuum. Inside are a set of metal vanes which are mounted on a spindle. WebReflected and absorbed photons do exert a radiation pressure, eg, comet tails, but it is small. A Crookes’ radiometer does not have a high enough vacuum or a sufficiently sensitive vane system to respond to the difference in radiation pressure. A device that does respond to photon pressure is the Nichols radiometer.
