Choose the appropriate resultant color. If no light is the result, choose none. Green light shines on a blue surface. What color is the reflected light? Magenta light shines on a red filter. What color is the transmitted beam? Red and blue light are combined in equal amounts. What color is produced? Answers can be white, red, green, blue, magenta, yellow, cyan, or none.
Green light shines on a blue surface. Depends on how each the surface and light is defined, but the standard answer is none. Blue surfaces absorb all colors except blue. Therefore, no light will reflect. Magenta light (there is no such thing as magenta light, it is a mixture of red and blue) shines on a red filter. The red filter absorbs blue and transmits red. Red is transmitted. Red and blue light are combined in equal amounts. Our eyes interpret this color as magenta.
