On the Cartesian plane the principle axes are the x horizontal axis and the vertical y axis whereas both axes cross each other at the point of origin which is at (0, 0)
----------
In an ellipse the major axis is the line that includes the most distant points on the ellipse; the minor axis includes the closest points. An ellipse is a two-dimensional object which can be generalised to three or more dimensions known as ellipsoids. The line that includes the most distant points on an ellipsoid is called the principle axis of that ellipsoid.

the principal or horizontal axis of a system of coordinates, points along which have a value of zero for all other coordinates.
Well this only occurs if the lens is parabolic. It is just a fundamental feature of a parabola to reflected an incident ray parallel to the principal axis through the focal point. That is why lenses etc are parabolic. I dont know if this answers your question (it probably doesnt) but oh well...
Next to the axis. Next to the axis. Next to the axis. Next to the axis.
The y- axis in the vertical axis and the x-axis in the horizantal axis
The conjugated principal point is a term used in optics to refer to the point where the chief ray of a light ray bundle passes through the optical axis after being reflected or refracted by an optical system. It is also known as the focal point or image point. The position of the conjugated principal point depends on the characteristics and parameters of the optical system.
The principal axis of a hyperbola is the straight line joining its two foci.
the imaginary line passing through the the center of curvature and pole is called the principal axis.
principal focus is the ray which diverge at a point on the other side of the lensPrincipal Axis lens have two centre of culvature,the line passing through them and joining these centres is called principal axis.
there can be two ways to cut a convex lens into two equal parts-- one, along the principal axis and another, perpendicular to the principal axis. If the lens is cut along the principal axis, then there will bo NO change in the focal length of the lens. But, if it is cut perpendicular to the principal axis, then the focal length will be twice the original one.
That passes through the principal focus of the concave mirror
It is reflected back parallel to the principal axis. (apex)
PRINCIPAL AXIS
longitudial transverse and medial
It reflects out through the focus.
the principal or horizontal axis of a system of coordinates, points along which have a value of zero for all other coordinates.
The refleted ray are meeting/intersecting at a point on the principal axis of the mirror.This point is called the principal focus of the concave mirror
If the object is placed on the principal axis of a concave mirror at a point between the focus and centre of curvature the image will form beyond the centre of curvature
