Convex lens is also known as converging lens .
please refer the attachment for the ray diagrams
1) At Infinity :
When object is placed at infinity the image is formed at focus.
Nature of Image :
- real
- inverted
- highly diminshed
2) Beyond 2F1 :
When object is placed beyond 2F1 the image is between F2 and C2
Nature of Image :
- real
- inverted
- diminished
3) At 2F1 :
When object is placed at 2F1 the image at 2F2
Nature of Image :
- real
- inverted
- same size as object
4) Between F1and 2F1
When object is placed beyond F1 and 2F1 the image is between beyond 2f1[ beyond c]
Nature of Image :
- real
- inverted
- magnified
