WAVES 1 (IMAGE) Rice University Caption A model by Rice University scientists shows how two positively charged spheres attached to springs are attracted to the electric field of light. Due to the motion of the spheres, the spring system scatters light at different energies when irradiated with clockwise and anticlockwise trochoidal waves.
