Radiometer in Arylic: kinetic energy from light in this Eames era vintage Lucite block sculpture with encased radiometer. Light heats up the "vanes" which then heat up the very thin gas left in the bulb- the black side of the vane is hotter than the colored side and any gas molecule that comes into contact with it flies off at a faster speed imparting impulse to the rotor. ➡️ Follow the link in my profile for info on where to buy radiometers and other amazing items featured here on @physicsfun #CrookesRadiometer #radiation #radiometer #light #lightmill #physics #physicstoy #photon #thermodynamics #science #kineticenergy #momentumtransfer #recoil #impulse #angularmomentum #scienceisawesome
