Question

What is the position of the object when position of the imageis at C?​

Answer 1

inverted and real image...

I hope you right answer

Answer 2

Ans.

1. When the object is placed at infinity,

2. When the object is placed beyond C (centre of curvature)

3. When the object is placed at C

4. When the object is placed between C and F (principal focus)

5. When the object is placed at F

6. When the object is placed between F and P (Pole)

The Object is Placed Beyond C

In this situation we consider two different rays emerging from the object. One parallel to the principal axis and the other directed towards the centre of curvature of the mirror. These rays after reflection from an image between the centre of curvature (C) the focus (F). The image thus formed is diminished, real and inverted.

Object is Placed Beyond C

The Object is Placed at C

Here the two rays emerging from the object are one parallel to the principal axis and other passing through the focus of the mirror. These rays after reflection from an image at point C. the image formed has the same size as that of the object and it is real and inverted.

Object is Placed at C

The Object is Placed Between C and F

Here the two rays considered are one parallel to the principal axis and other passing through the principal focus of the concave mirror. The image is formed beyond C. The image is larger compared to the size of the object and it is real and inverted.

Image Formation Tabular Data

Position of the object Position of the image Size of the image Nature of the image

At infinity At focus, F Highly diminished and pointed in size Inverted and Real

Beyond C Between F and C Diminished Inverted and Real

At C At C Same size Inverted and Real

Between C and F Beyond C Enlarged Inverted and Real

At F At infinity Highly enlarged Inverted and Real

Between F and P Behind the mirror Enlarged Erect and virtual
