Question

Draw any three ray diagrams to show how the size and nature of the
image of an object change when it moves from centre of curvature of
concave mirror towards the pole of the mirror

Sachin Pandey · Accepted Answer

Dear Student!! I When the object is at infinity

II When the object is behind the centre of curvature

III When the object is at the centre of curvature

IV When the object is between the centre of curvature (C) and focus (F)

V When the object is at focus (F)

VI When the object is placed between the focus (F) and the pole (P)

The discussion can be summarized in the table given below: Object position Image position Size of image Nature of image At infinity Focus (F) Point sized Real Beyond C Between F and C Small Real and inverted At C At C Same as that of the object Real and inverted Between C and F Behind C Enlarged Real and inverted At F At infinity Dear Studentghly enlarged Real and inverted Between F and P Behind mirror Enlarged Virtual and erect â€‹â€‹â€‹â€‹â€‹â€‹ Regards

Object position	Image position	Size of image	Nature of image
At infinity	Focus (F)	Point sized	Real
Beyond C	Between F and C	Small	Real and inverted
At C	At C	Same as that of the object	Real and inverted
Between C and F	Behind C	Enlarged	Real and inverted
At F	At infinity	Dear Studentghly enlarged	Real and inverted
Between F and P	Behind mirror	Enlarged	Virtual and erect
