The refraction from the sun causes morning and evening twilight, when light is visible even though the sun is below the horizon.
the sun is visible to us about 2 minutes before the sunrise & about 2 minutes after actual sunset because of atmospheric refraction.By actual sunrise, we mean the actual crossing of the horizon by the sun. The time difference between actual sunset & the apparent sunset is about 2 minutes. The apparent flattening of the sun"s disc at sunrise & sunset is also due to the same phenomenon .
Atmospheric refraction makes daylight hours appear longer at sunrise and sunset because the sun's apparent position is shifted due to the bending of light as it passes through Earth's atmosphere. This effect causes the sun to be visible even when it is geometrically below the horizon, creating the phenomena of sunrise and sunset.
it is because it suffers unequal refraction
Atmospheric refraction makes the Sun appear higher than it really is.
Sunrise = Alba, Sunset = tramonto
At sunrise and sunset the sun is near the horizon. The rays of light from upper & lower part of the periphery of the sun bend unequally on travelling through earth's atmosphere. That is why sun appear oval or flattened at sunrise and sunset. At noon sun is overhead. The rays of light from the sun enter earth's atmosphere normally. Therefore they suffer no refraction or bending on passing through. Hence the sun appears circular at noon.
The address of the Sunset Strip Branch is: 6600 Sunset Strip, Sunrise, 33313 2852
There is no nation where the sunrise and sunset occur at the same time. Sunrise and sunset happen at different times due to the Earth's rotation on its axis.
Because of atmospheric refraction. As the sunrise is two minutes early and sunsets is two minutes delayed.
The time of sunrise and sunset is VERY dependent on the position. And Florida is a big state. You can use the Sunrise Sunset calculator at the link below to calculate for yourself the time of sunrise and sunset for your location.
Sunrise, Sunset
At the north pole, there was no sunrise on that date. At the south pole, there was no sunset. Anywhere in between, the times of sunrise and sunset depended on the latitude of the location.
