Visible Light Colors and Energy Levels
Visible light is composed of rainbow colors. List the colors from lowest to highest energy.
(A) Red, orange, yellow, green, blue, indigo, violet.
(B) Violet, indigo, blue, green, yellow, orange, red.
(C) Red, orange, yellow, green, blue, indigo, violet, infrared, ultraviolet.
(D) Violet, indigo, blue, green, yellow, orange, red, infrared, ultraviolet.
What is the correct order of colors from lowest to highest energy? The order of colors from lowest to highest energy is red, orange, yellow, green, blue, indigo, and violet, aligning with option (A). Explanation: The colors of visible light, from the lowest to the highest energy, are listed as red, orange, yellow, green, blue, indigo, and violet. Therefore, the correct order from lowest to highest energy would be: red, orange, yellow, green, blue, indigo, violet. This sequence corresponds with the increasing frequency and decreasing wavelength of light within the visible spectrum. Infrared has a longer wavelength and lower energy than red, while ultraviolet has a shorter wavelength and higher energy than violet, but these are not visible to the human eye and are not included in the list of visible colors. Choice (A) Red, orange, yellow, green, blue, indigo, violet correctly lists the colors of the visible spectrum in order of increasing energy.
