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.
How much current flows in a 12-watt radio connected to a 120-volt circuit?
