Light is quantum which indicates the duality of particles and waves. Therefore, it is not possible to make a model of light to explain two antithetical characters at the same time. But, I succeeded to draw a model of light having simultaneously both characteristics of particles and waves based on “energy body theory”. The reason why light makes interference fringes in Young double slit experiment became clear by this. Particularly, the reason why interference fringes are made, even when photons are emitted one by one, if many photons are emitted, were also made clear. More, this photon model gives the reason to the phenomena such as reflection, refraction and invariable velocity of light.

Interference is a classic property of waves. It can be seen most clearly when a coherent wave is split into two partial waves that are then recombined to produce periodic variations in the measured intensity. These variations can be observed directly as a pattern of bright and dark interference fringes on a screen. The classic interferometer set-up is the Young's double-slit experiment: a small light source emitting in a narrow frequency band is placed on one side of the slits, and an interference pattern is observed at the screen on the other side (figure a). The fringes are bright where the partial waves interfere constructively, and dark where the interference is destructive.
