Web3.1 Images formed by Mirrors and Lenses • Images • Image formation by mirrors • Images formed by lenses Object-Image • A physical object is usually observed by reflected light that diverges from the object. • An optical system (mirrors or lenses) can produce an image of the object by redirecting the light. – Real Image – Virtual Image WebWhen a ray, passing through focus strikes concave or convex lenses, the reflected ray will pass parallel to the principal axis. Watch the video and learn more about image formation by lenses 14,248 Image Formation by Concave and Convex Lenses: Convex Lenses When an object is placed at infinity, the real image is formed at the focus.
WebThe reflection is inverted until the pencil passes the focal point. Real or Virtual - For mirrors, real images are formed in front of the mirror (can be projected onto something), Virtual images are theoretically formed behind the mirror and can only be seen when looking in the mirror. There is a projected image when the pencil is behind the focal point, and there is a … WebLens: Definition: The mirror is glass with one side silvery backing produces an image by reflection on only one surface.
