I promised in my earlier blog that I will prove the postulates of quantum theory to be true . They require a lot of time so , one postulate at one time .
Light is an electromagnetic wave that is composed of particles called photons .
If we bombard light on some materials like silicon( metalloids) we will get an electric current . This is photoelectric effect . This is because light hit electrons and made them move causing an electric current .
But , it was also found that this current , amount of electrons displaced depended on frequency rather than intensity of light .
So , it was postulated that light is an electromagnetic wave ( by Maxwell ) that is composed of photons .
