Optical wavelengths
Optical wavelengths refer to the range of light waves that the human eye can perceive, typically from about 380 nanometers (violet) to 750 nanometers (red). These wavelengths are part of the electromagnetic spectrum, which includes other types of radiation like radio waves and X-rays. Different wavelengths correspond to different colors of light: shorter wavelengths appear blue or violet, while longer wavelengths look red. Optical wavelengths are vital in various fields, including photography, astronomy, and fiber optics, as they help us understand how light interacts with materials and how we see the world around us.
