Päikeseloojangut

Päikeseloojangut, known in English as sunset, is the daily disappearance of the Sun below the western horizon. This phenomenon occurs as the Earth rotates on its axis, causing the Sun to appear to move across the sky. The visual spectacle of a sunset is often characterized by a vibrant display of colors, ranging from oranges and reds to pinks and purples. These colors are a result of Rayleigh scattering, where sunlight is dispersed by the molecules in the Earth's atmosphere. Shorter wavelengths of light, like blue and violet, are scattered more readily, while longer wavelengths, such as red and orange, penetrate the atmosphere more effectively, especially when the Sun is low on the horizon and its light travels through a greater thickness of air.

The timing and appearance of a päikeseloojangut can vary significantly depending on geographical location, time of year, and atmospheric conditions. For instance, sunsets are more dramatic and prolonged during seasons when the atmosphere contains more particles, such as dust or water vapor. In many cultures, päikeseloojangut is a significant event, often associated with the end of the day, a time for reflection, or a moment of natural beauty. It is a universal experience that unites people across the globe, marking the transition from daylight to twilight and eventually to night.
