In its simplest form, quantum theory describes light as consisting of discrete packets of energy, called photons However, neither a classical wave model nor a classical particle model correctly describes light; light has a dual nature that is revealed only in quantum mechanics

- The Basics of Light - Johns Hopkins University
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 - Encyclopedia. com
Light, of course, is more than color: it is energy, which travels at incredible speeds throughout the universe From prehistoric times, humans harnessed light's power through fire, and later, through the invention of illumination devices such as candles and gas lamps
