What is the range of the visible spectrum of light?

The visible spectrum of light is the portion of the electromagnetic spectrum that can be detected by the human eye, and it typically ranges from approximately 400 nanometers (nm) to 700 nanometers. This range encompasses all the colors of light that humans can perceive, which are red, orange, yellow, green, blue, indigo, and violet. Each color corresponds to different wavelengths within this range, with violet having the shortest wavelength around 400 nm and red having the longest at approximately 700 nm.

This understanding of the visible spectrum is essential in various fields, including physics, art, and optics, as it forms the basis for our perception of color and light. The other ranges provided do not accurately represent the wavelengths of visible light, as they fall outside of this established range for human vision.
