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

Given:

linear magnification= +3

To find:

Characteristics of the image formed

Explanation:

Let us know what is magnification

[tex]\underline{\tt Magnification:}[/tex]

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

[tex]\underline{\tt Conditions:}[/tex]

[tex]\bullet \sf m>1 \implies Enlarged \:image[/tex]

[tex]\bullet \sf m=1 \implies hi=ho[/tex]

[tex]\bullet \sf m<1 \implies diminished\: image [/tex]

[tex]\bullet \sf if \:value \:of \:m \:is \:negative \\ \implies \tt Image\: is \:real \:and\: inverted[/tex]

[tex]\bullet \sf if \:value \:of \:m \:is \:positive \\ \implies \tt Image\: is \:virtual \:and\: erect[/tex]

Now coming to the question,

[tex]\sf m=+3[/tex]

So,

Image formed is virtual,erect and enlarged image

It is a concave mirror
