Concave mirrors are mirrors that curve inward. Used to focus light, they reflect it inward toward one focal point. Concave mirrors show different types of images, depending on the distance between the mirror and the object reflected. Concave mirrors are used quite frequently in day-to-day life...
(v) and focal length. The figure shows an object AB at a distance u from the pole of a concave mirror. The image A 1 B 1 is formed at a distance v from the mirror. The position of the image is obtained by drawing a ray diagram. Consider the D A 1 CB 1 and D ACB [when ...
