- Light - Wikipedia
Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye [1] 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 What is the speed of light?

Light is at once both obvious and mysterious We are bathed in yellow warmth every day and stave off the darkness with incandescent and fluorescent bulbs But what exactly is light?
- Light - Simple English Wikipedia, the free encyclopedia
Light is a form of electromagnetic radiation that shows properties of both waves and particles It is a form of energy Light also keeps the Earth warm Light exists in tiny energy packets called photons Each wave has a wavelength or frequency The human eye sees each wavelength as a different color

Simply stated, light is nature's way of transferring energy through space We can complicate it by talking about interacting electric and magnetic fields, quantum mechanics, and all of that, but just remember--light is energy Light travels very rapidly, but it does have a finite velocity

Light is a form of electromagnetic energy that causes the sensation of vision The study of light is called optics and is classified in the following ways: It is the branch of physics which deals with the study of light It is mainly divided into three parts: Geometrical optics or ray optics: It deals with the reflection or refraction of light
