Answer 2

Answer:

• Green and red lights shine on a white screen, making it appear yellow.

Explanation:

• Red and green light work together to excite the red and green receptors on the retina of your eye. Yellow light can also excite those receptors! You see the colour yellow when the red and green receptors in your eye are activated, whether by a combination of red and green light or by yellow light alone.
• Red, blue, and green light colours combine to create white light when they are present in equal amounts.
• Because it reflects green wavelengths, the colour green appears green. Red has a longer wavelength than green, thus it absorbs more light when it hits a green object than it does when it reflects it, giving the hue of the object an appearance of black.
