But that same phenomenon can also sometimes make skies look red or orange. Here's a breakdown of how and why it all happens. But the science behind a blue sky isn't that easy.
One common example is the rainbow, when light from the Sun is reflected and refracted by water droplets. Some phenomena, such as the green ray, are so rare they are sometimes thought to be mythical. [2] Others, such as Fata Morganas, are commonplace in favored locations. Other phenomena are simply interesting aspects of optics, or
The misleading term "fire rainbow" is sometimes used to describe this phenomenon, although it is neither a rainbow, nor related in any way to fire. The term, apparently coined in 2006, [3] may originate in the occasional appearance of the arc as "flames" in the sky, when it occurs in fragmentary cirrus clouds. [4]
An aurora is a natural phenomenon. A natural phenomenon is an observable event which is not man-made. Examples include: sunrise, weather, fog, thunder, tornadoes; biological processes, decomposition, germination; physical processes, wave propagation, erosion; tidal flow, and natural disasters such as electromagnetic pulses, volcanic eruptions ...
A common optical phenomenon involving water droplets is the glory. [23] A glory is an optical phenomenon, appearing much like an iconic Saint's halo about the head of the observer, produced by light backscattered (a combination of diffraction, reflection and refraction) towards its source by a cloud of uniformly sized water droplets. A glory ...
A moonbow (also known as a moon rainbow or lunar rainbow) is a rainbow produced by moonlight rather than direct sunlight. Other than the difference in the light source, its formation is the same as for a solar rainbow: It is caused by the refraction of light in many water droplets, such as a rain shower or a waterfall, and is always positioned ...
