GREEN FLASH:
The Beautiful and Elusive Sunset Phenomenon:
The green flash is a phenomenon in which part of the sun appears to suddenly change color for about 1 or 2 seconds. The brief flash of green light is seen more often at sunset than at sunrise.
This fleeting spectacle is caused by the refraction of sunlight, which is particularly significant at sunset and sunrise, when the light travels through more of the Earth's atmosphere. The atmosphere bends the sunlight passing through it, separating the light into its different colors, much like a prism bends and splits sunlight into rainbows, according to Cornell University.
The various colors of light bend different amounts based on their wavelengths; shorter wavelengths (blue, violet and green) refract more strongly than longer wavelengths (yellow, orange and red). As such, blue and violet light are scattered by the atmosphere while red, orange and yellow are absorbed, leaving the green light the most visible during the few seconds when the sun sets below or rises above the horizon.
However, green flashes are not always green, according to Andrew T. Young at San Diego State University.Sometimes, when the air is especially clear, enough of the blue or violet light rays make it through the atmosphere and create a blue flash instead of a green one. Nonetheless, green is the most common hue reported and captured in photos.
There are four categories of green flashes: inferior mirage, mock mirage, subduct flash and green ray, according to an article published by the American Association for the Advancement of Science (AAAS). Nearly all green-flash sightings fall into the first two categories.
The rarest type of green flash is known as a green ray. In this instance, a beam of green light shoots straight up a few degrees from the green flash immediately after the sun sets for about a second. It's caused by the combination of hazy air and an unusually bright inferior, mock or subduct green flash.
How to see a green flash?
While there isn't an optimal condition that will guarantee a green flash sighting, the best way to potentially observe one is to go somewhere that provides a clear view of the horizon and is free of pollution, such as over the ocean.
Fun facts:
1. It would take a sloth one month to travel one mile.
2. 10% of the World’s population is left handed.
3. According to Amazon, the most highlighted books on Kindle are the Bible, the Steve Jobs biography, and The Hunger Games.
4. Bob Marley’s last words to his son before he died were “Money can’t buy life.”
5. A mole can dig a tunnel that is 300 feet long in only one night.
6. A hippo’s wide open mouth is big enough to fit a 4-foot-tall child in.
7. Drying fruit depletes it of 30-80% of its vitamin and antioxidant content
8. If you try to suppress a sneeze, you can rupture a blood vessel in your head or neck and die.
