The lowest wavelength of the visible light part of the spectrum occurs at about

The lowest wavelength of the visible light part of the spectrum occurs at approximately 380 nanometers (nm). This wavelength corresponds to the color violet, which is at the edge of the visible spectrum. The visible light spectrum ranges from about 380 nm to about 750 nm, with red light at the longer wavelengths (around 620-750 nm) and violet light at the shorter wavelengths (around 380-450 nm).

In the context of the electromagnetic spectrum, visible light is just a small portion, and it is situated between ultraviolet light (which has shorter wavelengths than visible light) and infrared light (which has longer wavelengths). Each color within the visible spectrum corresponds to a specific wavelength, and as the wavelength increases, the color transitions from violet to blue to green to yellow to orange and finally to red. Understanding these wavelengths is crucial, particularly in fields like optics, photography, and color theory.
