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
