Question

The linear magnification produced by a spherical mirror is + 3 state the characteristics of the image formed

Answer 1

Given:

linear magnification= +3

To find:

Characteristics of the image formed

Explanation:

Let us know what is magnification

$\underline{\tt Magnification:}$

Magnification is the ratio of height of the image to height of the object

(or)

It can also be defined as the ratio of -image distance to object distance

$\underline{\tt Conditions:}$

$\bullet \sf m>1 \implies Enlarged \:image$

$\bullet \sf m=1 \implies hi=ho$

$\bullet \sf m<1 \implies diminished\: image$

$\bullet \sf if \:value \:of \:m \:is \:negative \\ \implies \tt Image\: is \:real \:and\: inverted$

$\bullet \sf if \:value \:of \:m \:is \:positive \\ \implies \tt Image\: is \:virtual \:and\: erect$

Now coming to the question,

$\sf m=+3$

So,

Image formed is virtual,erect and enlarged image

It is a concave mirror
