solljusnedgång

Solljusnedgång, often translated as "sun setting" or "sunset," refers to the daily disappearance of the Sun below the horizon. This phenomenon occurs in the western sky as the Earth rotates on its axis. The apparent movement of the Sun across the sky is a result of our planet's rotation from west to east. As the Earth turns, different parts of its surface are presented to or turned away from the Sun.

The visual spectacle of a sunset is influenced by atmospheric conditions. During sunset, sunlight travels through a greater portion of the Earth's atmosphere compared to midday. This increased atmospheric path length causes shorter wavelengths of light, such as blue and violet, to be scattered away more effectively by air molecules. Consequently, longer wavelengths, like red and orange, become more prominent, painting the sky with warm hues.

The exact time of sunset varies depending on geographical location, time of year, and daylight saving time. Astronomical observatories and weather services track and report these times accurately. In meteorology, sunset is a precise definition, marking the end of daylight. Culturally, sunsets have been observed and celebrated for millennia, often associated with the end of the day and the transition to night. They are frequently depicted in art and literature, symbolizing various concepts such as endings, reflection, and the passage of time.
