An object is placed at a distance of `10 cm` from a convex mirror of focal length `15 cm`. Find the position and nature of the image ? |

Answer» Focal length of convex mirror, f = +15 cm Object distance, u = −10 cm According to the mirror formula, `rArr1/v=1/f-1/u` `rArr1/v=1/15-1/(-10)` `rArr1/v=1/15+1/10` `rArr=(2+3)/30` `rArr=5/30` `rArrv=6 cm` `"Magnification"=(-v)/u=(-6)/-10=0.6` The image is located at a distance 6 cm from the mirror on the other side of the mirror. The positive and less than 1 of magnification indicates that the image formed is virtual and erect and diminidhed. |
