Hello! Now, I will tell you about one of the natural phenomena in the world. What is that? That is Halo. Halo produced by sunlight interacting with ice crystals suspended in the atmosphere. It usually appears near the Sun or the Moon, street lighting, and sometimes on the surface of the earth. In general, it's caused by the presence of ice crystals in cold cirrus clouds that are already at an altitude of 5 to 10 km above the troposphere. What is the process of the occurrence of the halo phenomenon? The halo phenomenon begins with the presence of sunlight because the light is the subject of this phenomenon. Then the sun is refracted by the rod-shaped or prism-shaped ice surface. And sunlight breaks into several colors due to the effect of air dispersion. The sun's fragments are reflected in a certain direction and become a ring of light around the sun. Sometimes halo can appear near the surface of the earth when there are ice crysta...
