2、The Buddhist light of Mount Tai is actually a diffraction of light that appears under certain conditions.
1、This is due to diffraction of light.
3、However, for the actual optical system, its point image become a speckle because of diffraction of light and aberration.
5、Therefore, this paper proposes by experimental analysis that photons have the tension, similarly to water, and proposes a new model and an alternative hypothesis on diffraction of light.
4、Conclusion that result of diffraction of light is rectilinear propagation in limited condition is demonstrated from wave theory.
