In the visible spectrum, which color comes first?

In the visible spectrum, red is the first color when looking at the range of colors produced by white light when it is dispersed through a prism. The visible spectrum ranges from red at the longest wavelengths (approximately 620-750 nanometers) to violet at the shortest wavelengths (approximately 380-450 nanometers).

Red light has the longest wavelength of all the visible colors and is often associated with warmth and is one of the primary colors of light alongside green and blue. Understanding the order of colors in the visible spectrum is fundamental in fields such as optics, art, and various natural sciences, as it provides insight into how light behaves and how colors can be mixed and perceived.

The other colors in the choices follow red in the spectrum sequence, with violet having the shortest wavelength, which is why they do not represent the first color in the visible spectrum.
