Visible Light and the Electromagnetic Spectrum
Only a small part of the electromagnetic spectrum can be detected by the human visual system. Visible light wavelengths range from approximately 400 to 700 nanometers. We use electromagnetic energy for a variety of purposes, from warming our dinners to carrying on digital conversations.
