So your physics teacher is standing in front of the white screen in the front of the room. The room lights are off and you're in charge of the three colored spotlights. With a flip of a switch, you can shine any combination of red, green and blue light on the teacher. As you do, your teacher's clothes show their color and shadows are cast onto the white screen. How does the light that is shining on the teacher affect the color of his clothes and the color of the shawows? Launch the Interactive and find out.
