To determine the color of the screen, we need to understand how different colors of light interact with each other and with the screen.
When a red light source and a green light source shine on a white screen, the screen will appear yellow. This is due to the way light is perceived and how our eyes interpret different wavelengths of light.
White light is a combination of all visible colors. When red and green lights are combined, the wavelengths of these colors mix together and create a new color called yellow.
This phenomenon is known as additive color mixing because the red and green lights add up to create the perception of yellow. By adding more colors in different combinations, we can create a wide range of colors.
To confirm this explanation, you can conduct a simple experiment using colored flashlights or even the flashlight feature on a mobile phone. Shine a red light and a green light on a white surface, and you will observe that the resulting color on the surface indeed looks yellow.
