Crookes Radiometer Single For Physics Lab
The comprising partly evacuated glass bulb approx 70mm dia, with contained at its centre a fine pivot which supports four lightweight metal arms. One side of each vane is blackened, the reverse side is white. 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. 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.The unit is mounted on a round plastic base.
