Visible light Visible light is the portion of the electromagnetic spectrum that is perceptible to the human eye. It encompasses a range of wavelengths between approximately 380 to 750 nanometers, corresponding to the colors violet, indigo, blue, green, yellow, orange, and red. The various colors within this spectrum combine to create the white light that we observe. Each color is associated with a specific wavelength, with red having the longest wavelength and violet having the shortest. Visible light is essential for human vision, and it plays a significant role in various natural processes, including photosynthesis in plants. Technologies such as optics and imaging systems rely on visible light for a wide range of applications, making it a fundamental component of our daily experiences. |
