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.
