Web3 Answers. Sorted by: 1. A lens with spherical surfaces (i.e. surfaces that are a segment of a sphere) does not focus all parallel light rays onto a single point. Instead there is a focal surface called a caustic. This causes spherical aberation. As long as the lens curvature is small, i.e. the ray is near to the optical axis (paraxial rays ... WebA virtual image is on the same side of the lens as the object. A lens’s focal point is the point at which light rays meet after reflection or refraction. Converging lenses have a focal point on the side of the lens opposite of where the object is placed; therefore, converging lenses have a positive focal length. WebThe ray that passes through the focal point on the way to the lens will refract and travel parallel to the principal axis. Use a straight edge to accurately draw its path.
