Electromagnetic radiation in this range of wavelengths is called visible light or simply light.A typical human eye will respond to wavelengths from about 380 to about 750 nanometers. High-frequency sound waves are perceived as high-pitched sounds, while low-frequency sound waves are perceived as low-pitched sounds. Infrared and optical astronomers generally use wavelength.
