Answer» It is to be remembered that a convex MIRROR always forms the virtual, erect and diminished image. Given: Object distance, u=−10cm Focal length, f=15cm To find: Image distance, v From mirror formula : v1+u1=f1 v1−101=151 v1=151+101=15025 v=6cm Hence image will be formed 6 cm BEYOND the mirror, i.e virtual magnification m=u−v=−10−6=0.6 Hence it will be erect and diminis |
