Students explore how a color wheel can provide a useful model for determining the colors of light an object may absorb or reflect. Finally, students will investigate the color yellow. Many objects that appear yellow are not reflecting yellow light, but reflecting green and red. Students use their spectroscopes to search for objects that truly reflect yellow light.
