Green Flash from the Sun

Many people think this is just a myth. Other people think that this is true, but the reason is not clear. Adventurers are proud to see it. It is a flash of light from the sun. The truth is that there is a green flash and the reason is well understood. As the sun disappeared completely from sight, the last flash showed a splendid green color. Effects are normally only visible for shorter distances, farther distances and last only a few seconds. As the sun rises, you can see a flash of green, but it takes time to shoot.

The phenomenon of light called green flash is seen after sunset or just before sunrise. Flash is triggered by sunlight beneath the horizon bending towards the audience (usually by temperature reversal). The shorter wavelength (purple, blue, green) light bends more than the longer wavelength (yellow, orange, red) but the purple and blue light scatter more and leaves the light recognized as green . Ultraviolet rays from the sun are anticorrosive and can be used to disinfect tools and water. It also causes sunburn and results in other biological effects like vitamin D production and sunburn. Because ultraviolet rays are strongly attenuated by the ozone layer of the earth, the amount of ultraviolet light varies widely depending on the latitude, and some of the reasons for many biological indications, including changes in the color of human skin at various places on the earth is.

Green flashes often appear on the horizon of the Pacific Ocean, and when the atmosphere acts like a prism, it scatters the light at sunset so that only the green, sometimes blue or purple, remains in the eyes of the observer. The color does not flicker as the onion skin rises from the sun and blends into the sky. Last December, San Diego's amateur photographer Jim Grant took a picture of the lime spot of the sunset at the top of the sunset, highlighted by the smoke of the forest fire (see the top of this article reference). This image is widely distributed to social media and local media and at least one famous meteorologist has released as the best picture he has ever seen.
