A convex mirror has a focal length f. A real object is placed at a distance of f 2 from the pole. Find out the position, magnification and nature of the image.

The mirror formula is 1 v + 1 u = 1 f , The focal length is taken positive for convex mirror. The position of the object u = - f 2 , 1 v - 2 f = 1 f ⇒ v = f 3 , The magnification is m = - v u ⇒ m = - f 3 - f 2 ⇒ m = + 2 3 , The image formed is virtual, erect and smaller than object.

A small candle, $2.5 c m$ in size is placed at $27 c m$ in front of a concave mirror of radius of curvature $36 c m$ . At what distance from the mirror should a screen be placed in order to obtain a sharp image? Describe the nature and size of the image. If the candle is moved closer to the mirror, how would the screen have to be moved?
