Radiometer

How does it work?

 The sun makes the radiometer move  The vanes on the radiometer are black on one side and white on the other  The sun’s light is reflected by the white and absorbed by the black The Sun!

 When the light hits the white, the light reflects without much power  When it hits the black, it absorbs the light, making the atoms “kick” with more force  It would not work if the vanes were all the same color How it works

 Radiant to motion What is the energy transformation?

 When you wear black it is hotter, and white is cooler  Global warming  Solar panels are black to absorb more energy from the sun Real world examples
