When a red light source and a green light source shine on a white screen, the screen will appear yellow. This is because white light is composed of all the colors in the visible spectrum, and when red and green lights are combined, they result in the color yellow.

If a blue object is placed in front of the screen, it will appear black. This is because the blue object absorbs the red and green light that is shining on it, while reflecting or transmitting only the blue light. Since the blue light from the screen is already blocked by the blue object itself, the object will appear black.

When a red light source and a green light source shine on a white screen, the screen will appear yellow. This is because yellow light is produced when red light and green light are combined. To understand this, we can use the principle of additive color mixing.

Additive color mixing refers to the process of combining different colored lights to create new colors. When red light and green light are projected onto the white screen, the screen reflects both red and green light, while absorbing other colors. Our eyes perceive the combination of these two primary colors as yellow.

Now, if a blue object is placed in front of the yellow screen, it will appear black. This is because the blue object absorbs all colors of light except for blue. When the yellow light from the screen falls on the blue object, the blue object absorbs the yellow light and reflects only the blue light. Since the blue object does not emit or reflect any red or green light, we perceive it as black, as black is the absence of light.

In summary, the screen will appear yellow when the red light source and the green light source shine on it. And when a blue object is placed in front of the screen, it will appear black, as the blue object absorbs the yellow light and reflects only the blue light.
