When the position of an object is within focus between pole and focus of a concave mirror the size of images?

between its pole and focus

Describe the nature, size and position of the image formed in each case.

State one use of concave mirror bases on the formation of image as in case (i) above.

When an object is placed between the centre of curvature and the focus of a concave mirror, the image formed is real, inverted, and enlarged. This is illustrated as follows:

Here, the image A'B' of the object AB, placed between the centre of curvature and the focus of a concave mirror, is real and inverted.

Is there an error in this question or solution?

CONCEPT:

Concave mirror: The mirror in which the rays converge after falling on it is known as the concave mirror.
- A concave mirror is also known as a converging mirror.
- The focal length of a concave mirror is negative according to the sign convention.
All the position of object and images for the concave mirror are given in the below table:

Position of the object	Position of the image	Size of the image	Nature of the image
At infinity	At focus, F	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 F and C	Beyond C	enlarged	Inverted and real
At focus, F	At infinity	enlarged	Inverted and real
Between F and Pole	Behind the mirror	enlarged	Erected and virtual

corresponding image of the table:

EXPLANATION:

From the above table if the object is between the focus and pole of the mirror then the position of the image obtained will be behind the mirror (virtual image).
So the correct answer is option 3.
