Elements and Particles!

Over the years scientist and others of statue has studied the power of light and how it works and even that ordinary man in the street has wondered what causes light! Thomas Edison and Joseph Swan created the light bulb and between them both they fought each other in court battles to decide who has the right to patent the light bulb! Looking back to the Greeks of ancient times, individuals believed that light was a tributary of minute elements or particles because no one had really seen these minute elements or particles of light! Was it due to the infinitesimal size and their rapidness of movement that made them totally invisible to the naked eye or perhaps humans saw right through these very tiny particles!

 

 

Those of  whom studied light knows that light after all travels in a straight line and bounces off shiny objects in much the same way as a child bouncing a ball. The mathematician Einstein developed a complex explanation regarding the theory of light. Albert Einstein considered the photoelectric effect, in which ultraviolet light hits a surface and causes electrons to be emitted from the surface!

Energy Travelling Through Water!

Albert Einstein's theory states that light was made up of a stream of energy packets called photons. To understand light waves, one must begin through argumentation about a more familiar kind of wave the kind of wave we come across when we drop a stone or something of the kind in a pool of water. The point to focus on is to keep in mind keep that the waves in water is not made up of water itself, it is in fact waves made up of energy travelling through water! If a wave moves across a pool from left to right, this does not mean that the water on the left side of the pool is moving to the right side of the pool! The water has in point of fact remained where it was in the first place! Energy travels through the water in the form of the waves! Light waves are a little more intricate because light does not need an intermediary to travel through! Light can travel through nothingness and light waves consists of energy!

Swirling Computer Graphics!

And the form of electric and magnetic fields! Note: The power of energy lies in all things universally! These fields pulsates at right angles to the path of the movement of the waves at right angles to each other. For this reason light has both electric and magnetic fields and in most cases light is refer to as electromagnetic radiation! We see things every day, from the moment we get up in the morning until we

go to sleep at night! Light cause us to see everything around us! We treasure the glowing sunshine, those fine oil paintings, swirling computer graphics, the gorgeous sunsets, the rainbows, blue skies, and night time shooting stars! Humans rely on mirrors to make themselves personable! Have you ever stop to think what we've seen in the mirror knowing that we are not directly connected to it? In fact, we are seeing light that has left the object and has reached our eyes! Hence, light is all our eyes can really see! The wavelengths of the light we can see range from 400 to 700 billionths of a meter! However, it is noted that the full range of wavelengths included in the definition of electromagnetic radiation expands!
