The blue end of the visible color spectrum has wavelengths, and the red end has wavelengths.

The blue end of the visible color spectrum has wavelengths of 380 nanomenters, and the red end has wavelengths of 740 nanomenters.

Explanation:

The visible color spectrum is the range of colors (electromagnetic waves) that the most human eye can see. The human eye perceives colors with wavelengths of 380-700 nanometers. The color with the shortest wavelength is violet (380 nm) while the color with the longest is red (740 nm). Electromagnetic wavelengths outside the visible color spectrum are infrared, ultraviolet, X-rays, microwaves, and radio waves.
