The image formed by the concave mirror is observed to be virtual, erect and larger than the object. Where should be the position of the object relative to the mirror? Draw ray diagram to justify answer.
When the object is between Pole (P) and Focus (F) of a concave mirror:
- The image formed is behind the mirror, so it is virtual
- The image is erect
- The image is enlarged
