Please tell me about the type of image formed by concave and convex mirror and concave and convex lens in detail.(such as real ,magnified etc...)

Image formed by a concave mirror:
1) When the object is at infinity:
Position of object
Position of image
Size of image
Nature of image
At infinity
At focus F
Highly diminished, point – sized
Real and inverted
2) When the object is placed beyond the centre of curvature of the mirror:
Position of object
Position of image
Size of image
Nature of image
Beyond Centre of curvature C
Between focus F and C
Diminished
Real and inverted
3) When the object is at the centre of curvature:
Position of object
Position of image
Size of image
Nature of image
At cenre of curvature C
At C
Same size
Real and inverted
4) When the object is placed between the centre of curvature and the focus:
Position of object
Position of image
Size of image
Nature of image
Between C and F
Beyond C
Enlarged
Real and inverted
5) When the object is placed at the focus:
Position of object
Position of image
Size of image
Nature of image
At focus F
At infinity
Highly enlarged
Real and inverted
6) When the object is placed between the focus and the pole of the mirror:
Position of object
Position of image
Size of image
Nature of image
Between F and P
Behind the mirror
Enlarged
Virtual and erect
NOTE: Kindly post the other three (convex mirror, convex lens and concave lens) as separate queries.
