Question

A mirror in which at the minimum distance of clear vision (25cm) we can see our face in a1.5cm magnification? How far (in CM) is our face from the mirror?

Answer 1

Answer:

Our face is at a distance of 16.6cm from the mirror

Explanation:

Very Good question. Thanks for asking it.

According to question at least distance of distinct vision image we get that is our face

Image  distance is = V= 25cm

magnification =m=+1.5

nature of image :

---> virtual

---> erect

---> magnified.

According to question based on given data , the mirror could be concave where object is kept between P and F... we get magnified virtual and erect image behind the mirror

To find image distance :

m=-v/u

u= -V/m

=  -25/1.5

= - 16.6 cm

So our  face is  at a distance of 16.6cm from the mirror
