Applications of Lenses

Applications of Lenses. The Camera. If an object is beyond 2F, the image from a converging lens will be inverted, real, and smaller, and will always lie somewhere between F and 2F on the other side of the lens

Mirrors and Lenses:

Mirrors and Lenses:. Mirrors reflect the light. Lenses refract the light. Planar Mirrors and Lenses:. Flat reflective surfaces or flat surfaces that allow that transmission of light . The images produced are the same as the original object. Concave Mirror: Converges light rays.
