Question

the size of an object is 2cm.The magnification produced by the mirror is +1 . What is the size of the image

Answer 1

here you go ☆☆

m=h(i)/h(o)

1=h(i)/2

1×2=h(i)

i.e.

height of image =2

m is +ve,

image formed is virtual and erect.



hope it helps you.......:)

Answer 2

Answer : The size of the image is as same as that of object i.e. 2 cm.

Explanation :

It is given that,

Size of an object, $h=2\ cm$

Magnification, m = +1

We know that the magnification is defined as the ratio of the height of the image to the height of the object.

The positive value of magnification shows that the image is virtual and erect. It is formed by convex mirror.

$m=\dfrac{h'}{h}$

h' is the height of the image.

h is the height of the object.

$1=\dfrac{h'}{2\ cm}$

$h'=+2\ cm$

So, the size of the image is 2 cm.

Hence, this is the required solution.
