Holographic theory is an extension of physics, classical mechanics and special relativity. To comprehend these concepts, one must first have an adequate understanding of the innate properties of light. Electromagnetic radiation is mediated by the photon, which travels as a wave. The product of frequency and wavelength are equal to the speed of light, but the amount of radiant energy in a stream
. of photons is inversely proportional to wavelength. The intensity of light also diminishes according to the Inverse Square Law. As light travels in a wave, two photons can collide and either cancel out or amplify based upon their individual wavelengths. An important principle with respect to holographic theory is coherence. The light that a person observes throughout the course of the day is not coherent. It is a congregation of multiple wavelengths and different intensities. A laser beam, on the other hand, is coherent and only emits light with predefined parameters. A hologram itself is merely the medium in which light is contained and preserved, and these are usually photosensitive compounds. A holograph can be projected onto such a surface using two beams of light, one as a plane of reference and the other to capture the emission spectra of an object. Holographic theory can also refer to the holographic principle. This holds that the information contained in a volume of space is encoded on the boundaries of the region. This theory is still tentative to further research and observation, but there is empirical evidence that supports the theory. As light carries information, the emission of light onto a region describes the properties of objects within that region. This ties into concepts relating to mass spectrography. For example, the emission and absoption lines of Hydrogen are different from those of Oxygen and by analyzing the light reflected by a material, one can determine the composition of a material.
