What happens to a light ray that passes through the optical center of a convex LENS?
i have to do a diagram of a convex LENS. light rays are going into the convex mirror **not parallel ** to the principle axis.
In theory, the one going through the exact centre will not change direction.
However, because the lens will have some thickness, a light ray that arrives just a bit off the centre will be refracted just as it enters the glass, pass through the centre, then get refracted back on a parallel track as it comes out of the glass.
If will be in the same direction as before but not exactly on the continuation of it pre-entry line. It will be on a parallel line, offset by a tiny amount.
