MCQ
The image of an extended object, placed perpendicular to the principal axis of a mirror, will be erect if:
  1. The object and the image are both real.
  2. The object and the image are both virtual.
  3. The object is real but the image is virtual.
  4. The object is virtual but the image is real.
  • A
    Only $A$
  • B
    $A$ and $B$
  • ✓
    $C$ and $D$
  • D
    Only $D$
✓

Answer

Correct option: C.
$C$ and $D$



$\text{m}=\frac{-\text{v}}{\mu}=\frac{\text{h}_1}{\text{h}_0} ($for mirror$)$
Image will be erect mean height of the object and Image will e lies in same side. It mean if object isreal then Image in virtual. If object is virtula then Image is real.
