Want this question answered?
axis or optical center
A parallel light source will reflect off a concave mirror and go through a point inside the curve called the focus. Reflecting from a convex mirror will cause all light to bounce off in a straight line away from a focus point behind the mirror.
They are parallel lines
its called the intersept point when they don't meet its called a parallel line
If it is Parallel then no if there not parallel then yes.
The optical center of the lens is a point on the axis of a lens is the point where any ray passing through this point, the incident part and the emergent part are parallel. It is important for the proper refraction of light.
axis or optical center
A point on the horizon where parallel lines appear to meet is called the vanishing point.

Parallel planes.
I assume you mean that the parallel railway tracks meet.The point where Parallel lines meet is called infinity.BUTIn your example of of railway tracks the apparent meeting is caused by perspective and the point is called the vanishing point.
An illusion. Parallel lines, by their nature can never come together.
They are parallel lines
After they pass through the lens, they converge, meaning that they come together at a specific point.
its called the intersept point when they don't meet its called a parallel line
yap.. its just an optical illusion
The 38th parallel is referred as the separation point between North and South Korea. it is also called the demilitarized zone
