Then they realize that the end of pirates is nearing, caused by Lord Cutler Beckett(Tom Hollander). Will and Elizabeth join forces with Barbossa( Geoffrey Rush) to rescue Jack from Davy Jones' Locker.
The main characters are Captain Jack Sparrow (Johnny Depp), Will Turner (Orlando Bloom), and Elizabeth Swann (Keira Knightley). The exact way the light is refracted to cause a green flash is very specific, so a green flash doesn’t always appear even if viewing conditions are excellent.The end of the trilogy of Pirates. Conditions must be clear for a green flash to be observed (both in cloud cover, as well as dust and smog), and the actual horizon line must be clearly visible (best over the oceans). It can also be seen on our Pacific and Atlantic coasts (including the Cape), but this video was the best. Here is the best video I could find on youtube depicting an actual green flash in Fiji. While it does not create a sudden burst of green light that fills the sky as depicted in the movie, you can see a hint of only green in the last second before the sun completely crosses the horizon line. Therefore, the green light can make it to the observer’s eye, but other colors are blocked (the blues and purples are usually scattered too much in this scenario that they become invisible to the observer).īecause this phenomenon occurs only for a second, and is better seen with some magnification, it is called a “green flash”. When the sun is just below the horizon, those colors can no longer be seen, but the green is still able to bend with the curvature of the earth. The frequency of the color green allows it to bend more than reds, oranges, and yellows. Incoming sunlight is similarly refracted by the earth’s atmosphere, and bent slightly with the curvature of the earth. You are probably familiar with color prism shown below, which shows the various colors of visible light and how it is refracted into its rainbow of colors.
While rare, the green flash is an actual optical phenomenon caused by the way light scatters and bends in the atmosphere, known as refraction. The most relevant pop culture reference I could think of was from the movie Pirates of the Caribbean: At World’s End. Our last weather blog entry talked about “sun pillars,” and while researching that a little bit I stumbled across some material about “green flashes.” This is when a quick flash of green light appears at sunset just before the sun drops below the horizon.
