PPT-Visible light rays By: Elias Horton

Visible light description Generally visible light is defined as the wavelengths that are visible to most human eyes Electromagnetic radiation in this range of wavelengths is called visible light or simply light A typical human eye will respond to wavelengths from about 390 to 700 nm.
