Crookes radiometer
Original price was: $ 25.04.$ 24.77Current price is: $ 24.77.
The Crookes Radiometer, also known as a light mill, is a scientific apparatus consisting of a glass bulb containing a partial vacuum and a rotor with vanes coated black on one side and white or silver on the other. When exposed to light or radiant energy, the vanes rotate due to differential thermal transpiration, demonstrating principles of gas kinetics and energy conversion. It is commonly used for educational demonstrations of light pressure and thermodynamics.
