How does a concave lens bend light

WebThe concave lens is a diverging lens because it causes the light rays to bend away (diverge) from its axis. In this case, the lens has been shaped so all light rays entering it parallel to its axis appear to originate from the same point, F, defined to be the focal point of … WebDec 28, 2024 · To complete the ray tracing process for a concave lens, note that any light ray from the object that travels parallel to the optical axis of the lens will be deflected, so it appears to have originated from near the focal point of the lens, on the same side of the lens as the object itself.
