Answer 1

The order of colors on a traffic light from top to bottom is Red, Yellow, Green.

Step-by-step explanation:

The order of colors on a traffic light from top to bottom is Red, Yellow, Green. The visible light spectrum consists of different wavelengths, and we perceive these wavelengths as different colors. Red has the longest wavelength, followed by orange, yellow, green, blue, indigo, and violet. This can be remembered using the mnemonic ROY G BIV. Therefore, on a traffic light, red is at the top, followed by yellow, and then green.
