उत्तर
OBJECT PLACED IN FRONT OF CONVEX MIRROR :
Place the object anywhere in front of convex mirror image formed is
- Between pole and focus ← position.
- Diminished ← size.
- Upright (erect) and virtual ← nature.
As the object is moved away from the mirror, the image shifts towards the focus and decreases in size but is (diminished)
