- Light - Wikipedia
Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye [1][2] Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz

Light is electromagnetic radiation that can be detected by the human eye Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10 −11 metres to radio waves measured in metres

But what exactly is light? We catch glimpses of its nature when a sunbeam angles through a dust-filled room, when a rainbow appears after a storm or when a drinking straw in a glass of water looks disjointed

Is light a wave or a particle? How is it created? And why can’t humans see the whole spectrum of light? All your questions answered
- What is Light? - Las Cumbres Observatory
Light is just one form of electromagnetic radiation, or electromagnetic waves These waves are all around us and come in many sizes The largest electromagnetic waves, with wavelengths from a few centimeters to over 100 meters are called radio waves
- Light - New World Encyclopedia
The study of light and its interaction with matter is termed optics The observation and study of optical phenomena such as rainbows and the aurora borealis offer many clues about the nature of light as well as much enjoyment
- The Nature of Light – The Physics Hypertextbook
Light is a transverse, electromagnetic wave that can be seen by the typical human The wave nature of light was first illustrated through experiments on diffraction and interference
