One of the remarkable discoveries by the world-renowned scientist, Albert Einstein, is the Photon Theory of Light. According to the theory, light is an electromagnetic radiation with a wavelength that is visible to the human eye. A photon is an elementary particle that defines the light observed. According to Einstein, there are three basic or fundamental dimensions to be considered, when studying the Photon Theory of Light. They are:
1) Intensity: The property of intensity that the light displays is related to the subject's perception of the brightness of the light.
2) Frequency: The property of frequency that is displayed and observed is actually the color of the light perceived.
3) Polarization: Contrary to the other two, the property of polarization of the light observed is only weakly perceptible, under ordinary circumstances.
According to Albert Einstein's Photon Theory of Light, the intensity of light shining on a metal determines the ability of the surface to reflect and deflect the light. It provides for observation the ability of a metal surface to receive and throw out the light effectively and in an intensity that is observed to be stronger than any other ordinary surface material. The focus of the source of light and the surrounding light also define the intensity observed and fulfill a fundamental dimension of the study advocated by the theory.
