Q31 of 31 Page 67

An object is placed at a distance of 10cm from a convex mirror of focal length 15cm. Find the position and nature of the image. (AS7)

Focal length (f) = 15 cm

Image distance(v)= ?


Object image (u) = - 10cm


Using mirror formula :






v = 150/25 cm = 6cm


Thus, the image will be formed behind the mirror at a distance of 6 cm from the mirror. The image is virtual, erect & diminished.
