Crookes Radiometer

The unit is mounted on a round plastic base.

One side of each vane is blackened, the reverse side is white.

Comprising partly evacuated glass bulb approx 70 mm diameter, with contained at its centre a fine pivot which supports four lightweight metal arms.

Infrared radiation heats the black faces of the vanes more than the white, causing a pressure difference on either side of the vanes which drives the vanes round, providing a pleasant visual demonstration of several physical effects.

Discussion of the mechanism turning the vanes covers several areas of physics including: thermal radiation and absorption; thermal transfer; air pressure; and momentum of gas molecules.
