Visible light is the portion of the electromagnetic spectrum that can be seen by the human eye, typically ranging from wavelengths of approximately 380 nanometers (nm) to 750 nm. It is arranged in a spectrum from violet (around 380-450 nm), blue (450-495 nm), green (495-570 nm), yellow (570-590 nm), orange (590-620 nm), to red (620-750 nm). Each color corresponds to a specific range of wavelengths, with violet having the shortest wavelengths and red having the longest. This arrangement creates the colorful spectrum we observe in rainbows and other natural phenomena.
