Explanation:
Have you ever seen an entire rainbow?
From the ground, typically, only the top portion of a rainbow is visible because directions toward the ground have fewer raindrops.
From the air, though, the entire 360-degree circle of a
rainbow is more commonly visible.
Pictured here,
a full-circle rainbow was captured over
the
Lofoten Islands of
Norway
in September by a drone passing through a rain shower.
An observer-dependent
phenomenon
primarily caused by the
internal reflection
of sunlight by raindrops, the rainbow has a full
diameter of 84 degrees.
The Sun is in the exact
opposite direction from the rainbow's center.
As a bonus,
a second rainbow
that was more faint and color-reversed was visible outside the first.
