  • Vanes in the Radiometer are alternately dark and light in color
  • When the light strikes the vanes it transfers heat to each one but not at the same degree
  • Lighter vane reflects the rays and darker vane absorbs the rays
  • Stronger the light, the more energy there is causing the vanes to spin faster
