An illuminated vertical object is initially placed on the principle axis of a converging lens and 32 cm from it

      

An illuminated vertical object is initially placed on the principle axis of a converging lens and 32 cm from it. The focal length of the lens is 15 cm. The object is now placed at a point 12 cm from the lens and on the same side. State two changes other than magnification that are observed on the image formed due to this change.

  

Answers

---

1. Image changes from real to virtual

2. Image changes from inverted to upright

3. Image changes from behind lens to the same side as object.
