what are visible light waves for

Visible light waves are a form of electromagnetic radiation that is detectable by the human eye. These waves have a specific range of wavelengths, typically between 380 and 750 nanometers, which correspond to different colors ranging from violet to red. These waves enable us to see and perceive the colors, shapes, and textures of objects in our surroundings. They also play a crucial role in various biological processes, such as the regulation of the sleep-wake cycle and the production of vitamin D in the human body.
