Do we know the sun is the source of light !!! light energy is the energy produced or emitted from the light source. As we know, the sun is the source of the greatest energy of light in the world.
For example of this energy are sun, fire, stars, electric lights, candles, flashlights, lightning and so forth. With this energy then when we are in a dark place will look bright. Sometimes this energy is also referred to as solar energy because the actual source of the illumination comes from solar power or what we often refer to as the sunlight which is the biggest star in the universe.
Sunlight emits most of the radiation called electromagnetic. While humans themselves can only see a fraction of this one energy, which is known as the "visible light". Light energy itself can be defined as the energy in the form of an electromagnetic wave that has a wavelength of 380 to 750 nano meters based on the visible human eye itself.
