A Crookes radiometer, known to some as a light mill, is a pretty low-tech apparatus consisting of a light bulb with a partial vacuum inside (very few air particles inside the bulb compared to normal air we breathe) and a bunch of vanes attached to a spindle. It was designed by Sir William Crookes in 1873—he was doing chemistry experiments in ...

When Sir William Crookes developed a four-vaned radiometer, also known as the light-mill, in 1873, it was believed that this device confirmed the existence of linear momentum carried by photons1 ...

A radiometer (also known as a light-mill, and more precisely as a Crookes radiometer) was developed by Sir William Crookes in 1873 while investigating infrared radiation and the element thallium. Crookes submitted a paper using differential radiation pressure to describe the operation of the radiometer. The paper was reviewed by Maxwell, who accepted Crookes's …

Sir William Crookes. Sir William Crookes invented this type of radiometer in 1873 while he was studying the element thallium. The radiometer is a glass bulb with a partial vacuum, which means that there is very little air left inside the glass bulb.A rotor with four light weight metal vanes is mounted on top of a spindle so that they are free to rotate with very little friction.

A radiometer used to demonstrate that radiant energy from the sun can produce motion; a miniature four-vane windmill is mounted in a glass-envelope vacuum tube, with each vane polished on one side and black on the other.

It is named for Sir William Crookes who first devised it in 1873. 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.
