Question

Show the following in the form of a flowchart.
$\left( 1 \right)$ Images formed by a concave mirror.
$\left( 2 \right)$ Image formed by a convex mirror.

Answer 1

Hint:In this question we need to represent the image formation using concave mirror and convex mirror in the form of flowchart. In the case of image formation using a concave mirror there are six different positions of the object whereas in the case of image formation by the convex mirror there are two different positions of the object as shown in the tabular column below. Based on this position of the object we need to write the position of image, size of the image and nature of the image.

Complete answer:
$\left( 1 \right)$ Images formed by a Concave mirror

Position of object	Position of image	Size of image	Nature of image
At infinity	At the focus $\left( F \right)$	Highly diminished	Real and inverted
Beyond the centre of curvature $\left( C \right)$	Between $\left( F \right)$ and $\left( C \right)$	Diminished	Real and inverted
At centre of curvature $\left( C \right)$	At $\left( C \right)$	Same size	Real and inverted
Between $\left( C \right)$ and $\left( F \right)$	Beyond $\left( C \right)$	Enlarged	Real and inverted
At Centre of curvature $\left( C \right)$	At infinity	Highly enlarged	Real and inverted
Between $\left( F \right)$ and $\left( P \right)$	On the same side of object	Enlarged	Virtual and erect

$\left( 2 \right)$ Images formed by a convex mirror

Position of object	Position of image	Size of image	Nature of image
At infinity	At the focus $\left( F \right)$,behind the mirror	Highly diminished	Virtual and erect
Between infinity and pole	Between pole $\left( P \right)$ and focus $\left( F \right)$ , Behind the mirror	Diminished	Virtual and erect

Note:The nature of the image formed by the concave mirror is real and inverted except in the last case that is when the object is placed between the focus and pole.Whereas the nature of the image formed by the convex mirror is always virtual and erect. In all the cases we get the diminished image in the case of convex mirrors.
