In order to see, there must be light. Light shines on an object, then bounces off, or reflects, back to our eyes. Our eyes are sensitive to a certain kind of light called visible light. Visible light is all the colors (red, yellow, blue, etc.) that we can see. But there are many other kinds… From wonders.physics.wisc.edu
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. From newworldencyclopedia.org

When light hits a transparent object, it passes through it almost completely without making a significant shadow. Light is a form of electromagnetic radiation that shows properties of both waves and particles. From simple.wikipedia.org
WHAT IS LIGHT? A GUIDE TO WAVES, PARTICLES, COLOUR AND MORE
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. From sciencefocus.com
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. From blair.pha.jhu.edu

The main source of natural light on Earth is the Sun. Historically, another important source of light for humans has been fire, from ancient campfires to modern kerosene lamps. With the development of electric lights and power systems, electric lighting has effectively replaced firelight. From en.wikipedia.org
