In terms of visible light, which of the following colors appears last in the spectrum?

In the visible light spectrum, colors are arranged based on their wavelengths. Violet light has the shortest wavelength, while red light has the longest. The visible spectrum is typically represented by the acronym ROYGBIV, which stands for red, orange, yellow, green, blue, indigo, and violet, arranged from longest wavelength to shortest.

When considering which color appears last in the spectrum, it's important to recognize that "last" refers to the position from the red end of the spectrum toward the violet end. Thus, violet, being at the extreme end of the spectrum, does indeed appear last.

Colors like blue, green, and yellow occupy positions that are before violet in the spectrum. Blue, for instance, is situated between green and violet, which means it appears earlier than violet. This applies similarly for green and yellow. Therefore, violet is the correct answer as it is the final color in the visible light spectrum.
