Have you ever watched the sun go down over the sea horizon? Yes, of course. Did you wait for the moment, the code is top the edge of the solar disk touched the eye and then disappeared? Surely. But maybe you noticed (if the sky was cloudless and absolutely transparent) an amazing phenomenon that occurs in that the moment when the radiant Helios casts his last ray? If no, then do not miss the opportunity to make such an observation – and then in a ray of amazing green will hit your eyes. This unique you will not find a shade either in the palette of nature itself or on canvases of painters.
Jules Verne has a novel called “Green Ray”, the heroine which pursues this rare occurrence throughout the archipelago The Hebrides, but alas, in vain …
The green beam is an optical effect that can lasts from one second to five minutes and is manifested by a flash green, and sometimes blue. As we said, arises he is at the moment when the solar disk disappears beyond the horizon (usually by sea).
You can observe the green beam in the presence of three conditions: open horizon (at sea in the absence of unrest or in the steppe), clean air and cloudlessness.

The usual duration of this phenomenon is several seconds, however, this time can be increased if, when the effect quickly run up to a hill (in the steppe) or go from deck to deck of a ship so fast that eye position relative to the beam persisted. American pilot and Researcher Richard Byrd has been able to observe a green beam on for 35 minutes. It happened during the expedition to the South pole at the end of the polar night: then the edge of the first appeared The solar disk moved along the horizon.
Everyone who saw the green ray admires its unusual emerald tone. Perhaps this extraordinary, just fantastic cleanliness green tone and prompted the scientist, a great specialist in holography and all kinds of lasers by William Cohn on an interesting thought. He began to seek an explanation for this natural phenomenon in radiation. excited atoms of, say, oxygen upon their transition to normal metastable state, due to which radiation appears with a wavelength of 0.5585 microns. Nevertheless, the second is incomprehensible to the end, namely, how does such a natural laser arise.
