When visitors stand on the top of Mount Emei and stand back to the sun, and the front and bottom are filled with clouds, sometimes they see an outer red and purple inner halo on the sky below the front, showing the viewer in the middle. People move, people go to the air. Even if the two hug each other, each person can only see their own figure. This is the magical Buddha phenomenon in Mount Emei, Sichuan. How exactly is this Buddha formed?
Buddha light is the most peculiar natural phenomenon in the world-famous sunrise, clouds, Buddha light and holy lights. More than 60 times, more than 80 times a year, so people call it Emei Baoguang. For thousands of years, Emei Baoguang has been well-known in ancient and modern China and abroad. The rendering of Buddhism has made it more legendary and mysterious, attracting countless curious people. Many people have tried to make scientific explanations of the mysterious Buddha light .
As a natural phenomenon, it has been the past century that Fo Guang has attracted the attention of Chinese and foreign scientific circles and started special research. Chinese scholar Professor Wei Fuping believes that the Buddha s light is formed by the spreading phenomenon of the sunlight through the edges or gaps of obstacles, that is, the effect of diffraction. When the clouds are thick, after passing through the clouds, sunlight will be reflected by water droplets or ice crystals deep in the clouds. When this reflection passes through the surface of a cloud, the diffraction phenomenon that occurs at the edge of tiny water droplets will cause a part of the light beam to deviate from the original radiation direction. The angle of deviation is inversely proportional to the diameter of the water droplets and proportional to the wavelength of each color of light. As a result, different monochromatic lights gradually spread out, and a colored halo appeared in front of people s eyes. Why is a ring-shaped photoreaction different from a rainbow that also forms a ring? This is because only the monochromatic light located on a certain light cone surface can be seen by human eyes, and the position at which they stand, that is, the viewing angle of the light cone is about 9 degrees, and the rainbow The viewing angle is 84 degrees. At the same time, when the light is diffracting, the shorter the light wave is, the larger the deviation angle is. Therefore , the hierarchical distribution of the color of the Buddha light is generally purple outside, and the red is closer to the center. The degree of color discrimination gradually decreases to the center of the aura. Like a stained glass mirror. Because of the complex effects of diffraction and diffuse reflection, the hue of the Buddha s light is often not as clear and clear as a rainbow, but fused together moistly like a watercolor. Why do you only see yourself? The main reason is that although there are many water droplets and ice crystal points in the clouds, the auras that people see each other are just the result of the action of the water droplets or ice crystal points on the light cone surface that their eyes regard as the apex. Just as they are respectively looking at a small round mirror, they naturally see their respective figures. As for the appearance of shadows moving with people and people going to the air, it is the principle of photographing light in the Buddha s light. There is no scientific explanation so far, and further research and discussion are needed to give everyone a clear understanding.
