Visible light is a specific portion of the electromagnetic spectrum that is visible to the human eye. It has a wavelength range of approximately 400 to 700 nanometers and is responsible for the colors we see in the world around us. Research in the area of visible light encompasses a wide range of topics, including the study of optics, photonic technologies, color perception, and the development of devices that utilize visible light for communication, imaging, and sensing applications. This research area is important for advancing our understanding of light and its interactions with matter, as well as for the development of new technologies that leverage the unique properties of visible light.
