설명
Visible light spans roughly 380 nm (violet) to 700 nm (red). Radio waves can have wavelengths of hundreds of meters, while X-rays measure in tenths of a nanometer. Wavelength and frequency are inversely related through wave speed: λ = v/f. In fiber optics, 1,550 nm is the standard wavelength for long-distance data transmission.
