What Is The Light?
Without light we may not notice the objects around us, however, so we still don't know exactly what that light. we know that light is a form of energy, its speed can be measured from how light it behave as we know it, we also know that the white light that we see it is not a special light, but rather a mixture of various colours called "spectrum".

we also know that the colours that cannot be seen on the object itself, but with the help of light we can see it, green piece of paper appears green because it absorbs all the colors except green, which is reflected into our eyes.
blue glass only allow blue light penetrates her, while other colours are absorbed into the material glass was, sunlight is energy, the hot sun that, when focused by a lens, it could cause a fire.
light and heat reflected from the white objects and absorbed by the black objects, which is why white clothes it cooler when we wear black clothing than in the agency.
but, how the nature of light is it actually? the first man who tried to seriously want to know and have managed to uncover some secrets of this light is Sir, Isaac Newton.
Sir. Isaac Newton argued that light is made of "corpusal", which is a sort of red blood cells or white blood cells in the blood of us, its shape is like a small bullet fired out of a light source it.
however as objects that can emit light could not be explained on the basis of this theory, and then appeared another person named Huygens by bringing another explanation about light, Huygens developed the so called theory of wave of light.
according to Huygens, the light was propagated by impulse energy of waves, not unlike a grain of pebbles that we throw into a pond ripple the waves causing above the water surface.
whether it's light or wave-shaped corpusal, continued to be a dubious debate materials over the past 150 years, but that wave theory appears to be the single most widely accepted by scholars, then one find something about the way the light to behave, so the theory that first it is so dispersed.
in a side where is the science now resting its founding about light? now these experts argue that the light was good to behave as a particle and as a wave.
experiments can be conducted to prove that light is one element of it, so not yet seem a satisfactory answer is firmly against what is actually light it.
