Parallel to the principal axis
Most of the time, a light ray passing through the atmosphere in any direction curves away from its original direction toward the earth's surface. Occasionally, light can proceed straight through the atmosphere with no change in direction. Rarely, it can bend away from the surface.
A diverging lens can only produce a virtual image, because the light passing through a diverging lens never converges to a point. The virtual image produced by a diverging lens is always right-side-up and smaller than the original object. The image and the object viewed are always on the same side of the lens. Diverging lenses are used as viewfinders in cameras.
The road through the tires of the car. It is caused by the new bias of the tires allowing the car to proceed only in the assigned direction.
Concave lenses would have only diverging action. So parallel beam of light after passing through a concave lens have to go diverged. Only converging waves could produce a real image on a screen. But diverging rays cannot meet at a point and so they appear to come from a point and hence that point is taken to be the virtual image
Light can not change direction by passing from one kind of mater to another. In fact, light can only pass through its own type of matter, which is when things like light can go through each other (and only a few types of matter can do that), but even in that case since it can go through, it can't be bent in angle by passing through.

Violet will get deviated the most.
The Bárðarbunga volcano in Iceland (currently erupting) is an example. A diverging plate boundary passes through the island of Iceland.
spine is reference direction and spline is curve, but in GSD spine is curve passing through plane.
