Question

select the correct answer.
which sequence shows all the colors of visible light arranged from shortest to longest wavelength?
a. red, yellow, orange, blue, green, indigo, and violet
b. red, orange, yellow, green, blue, indigo, and violet
c. violet, indigo, blue, green, yellow, orange, and red
d. violet, indigo, green, blue, orange, yellow, and red

Explanation:

To determine the correct sequence of visible light colors from shortest to longest wavelength, we recall the order of the visible light spectrum. The correct order (from shortest to longest wavelength) is violet, indigo, blue, green, yellow, orange, red. Let's analyze each option:

• Option A: Incorrect order (mixes up red, yellow, orange and has wrong positions for blue, green).
• Option B: This is from longest to shortest (starts with red which has longer wavelength), so incorrect.
• Option C: Matches the order of shortest (violet) to longest (red) wavelength.
• Option D: Incorrect order (green and blue are misplaced, orange and yellow too).

Answer:

C. violet, indigo, blue, green, yellow, orange, and red
