Web• A concave mirror caves in on the object; whereas • A convex mirror flexes away from the object. Each mirror has a radius of curvature r (which is infinite for the plane mirror) and a focal length f = 1 2 r. By convention, distances are measured, along the central axis, as positive from the mirror in the direction of the object and Web36. Focal Length of Lenses. The focal length, ƒ, is the image distance that. corresponds to an infinite object distance. This is the same as for mirrors. A thin lens has two focal points, corresponding. to parallel rays from the left and from the right. A thin lens is one in which the distance between.
WebNo image is formed. Light rays from the same point on the object will reflect of the mirror and neither converge nor diverge. After reflecting, the light rays are travelling parallel to each other and do not result in the formation of an image.

If the object is further away from the mirror than the focal point, the image will be upside-down and real---meaning that the image appears on the same side of the mirror as the object. The closer the object comes to the focal point (without passing it), the bigger the image will be. green glass hatWebWithout signs we have to explicitly mention we're dealing with a concave mirror, or a convex mirror, or the images in front of the mirror, or the images behind the mirror.
