Question

"If a blue filter is placed in between the yellow filter and the white screen, predict the light color that might be observed on the white screen. Explain your answer."

a) Green
b) Purple
c) White
d) Blue

Answer 1

The color observed on the white screen when a blue filter is placed between a yellow filter and the screen is green, as the blue filter allows only green light from the yellow light to pass through.

Step-by-step explanation:

If a blue filter is placed in between the yellow filter and the white screen, the color that might be observed on the white screen would be green. This is because the yellow filter would only allow yellow light (which is comprised of red and green light) to pass through, while the blue filter would absorb all of the light except for the blue component. However, since there is no blue component in yellow light, only the green part of the yellow light would be able to pass through the blue filter and be observed on the screen.
