Visible light is a part of the electromagnetic spectrum that can be seen by the human eye. It consists of different colors, which can be observed in a rainbow, ranging from red to violet. Each color has a specific wavelength, with red having the longest wavelength and violet the shortest. This type of light is essential for various processes, including photosynthesis in plants, which allows them to convert sunlight into energy. Additionally, visible light enables us to see our surroundings, as it reflects off objects and enters our eyes, allowing our brains to interpret the information.
