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 …

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. WebCrookes' radiometer is the result of serendipity, the act of making unexpected discoveries when looking for something else. In this case, Crookes was looking for a means to weigh …
WebWhen molecules in the air hit the vanes heat energy is transferred to them. What is the use of Crookes radiometer? Today the device is mainly used in physics education as a demonstration of a heat engine run by light energy.
