The visible light spectrum ranges from:

The visible light spectrum encompasses the wavelengths of electromagnetic radiation that can be seen by the human eye, which is typically defined as ranging from approximately 380 nanometers (nm) to 750 nm. This range includes all the colors visible to us, from violet (around 380 nm) through blue, green, yellow, orange, and red (up to about 750 nm).

The choice indicating this range correctly identifies the limits of human vision and is widely accepted in scientific literature. This range allows for the understanding of how light interacts with various materials and is crucial for various applications in fields such as optics, photography, and medical technologies.

Other ranges provided may miss the true extent of visible light. For example, suggesting a range that starts below 380 nm or goes beyond 750 nm either includes ultraviolet light or infrared light, both of which are outside the visible spectrum for humans. Understanding this spectrum is essential for professionals working with lasers and light technologies, as certain applications depend on how we perceive different wavelengths.
