Ray diagram of concave mirror object between c and f

Today we will discuss the ray diagram of a concave mirror object between c and f. To draw the diagram, we just follow the rules for making a ray diagram for a concave mirror.

 

Image formation by concave mirror

 

Steps to draw to ray diagram

1.   Draw the diagram of a concave mirror

2.   Place the object at the given position

3.   Follow the rules for making a ray diagram

 

Draw the diagram of concave mirror

Place the object at the given position

 Now we place the object (↑) between C and F.

Rules for making ray diagram

A light ray from point ‘A’ of the object incident parallel to the principal axis on the concave mirror.

The second light ray from the same point (A) incidents on the mirror at a certain angle (incident ray goes away from the principal axis).

The parallel incident ray passes through the focus point (F) after reflection.

The second incident ray passes through point C after reflection.

Both the reflected rays meet beyond C (between C and infinity) so the image is formed beyond C.

 

Position of image	Beyond C(between C and infinity)
Nature of image	Real and inverted
Size of image	larger than object
