The visible spectrum refers to the range of light wavelengths that the human eye can detect, typically from about 380 to 750 nanometers. This spectrum includes all the colors we can see, such as red, orange, yellow, green, blue, and violet. Each color corresponds to a different wavelength, with red having the longest wavelength and violet the shortest. When sunlight passes through a prism, it splits into the visible spectrum, creating a beautiful rainbow. This phenomenon helps us understand how light interacts with different materials. The visible spectrum is essential for various fields, including art, photography, and even biology, as it influences how we perceive our world.
