a red light source and green light source shine on a white screen. so
if a blue object is placed in front of the screen, what color will it be? explain?
The combination of red and green light makes yellow light. That is what hits the screen.
Putting a blue object in the combined light beam removes the red and the green from the light that is reflected by the object. That leaves only black.

When a red light source and a green light source shine on a white screen, they combine to create white light. The white light is made up of all the colors of the visible spectrum, including red, green, and blue components.
Now, when a blue object is placed in front of the screen, it will absorb all the colors of light except for blue. Since the blue object absorbs red and green light, only the blue light from the white light source will be reflected or transmitted by the object.
As a result, the blue object will appear blue to our eyes because it only reflects or transmits blue light, while absorbing all the other colors. So, the color of the blue object will remain blue when illuminated by the red and green light sources shining on the white screen.
To determine the color of the object when a red and green light source shine on a white screen and a blue object is placed in front of it, we need to understand how colors interact.
When white light hits an object, the object absorbs certain colors and reflects others. The color we perceive is the result of the reflected light reaching our eyes.
In this case, the red and green light sources shine on the white screen. The screen reflects both red and green light, resulting in white light.
Now, when a blue object is placed in front of the screen, it will selectively absorb all colors except blue. The blue object will absorb the red and green light, which means there will be no red or green light reflected from the object.
Ultimately, the blue object will only reflect blue light, which our eyes perceive as the color blue. Hence, the blue object will appear blue when placed in front of the screen illuminated by red and green light.
