Question

Q. What is the nature of image formed by a concave mirror if the magnification produced by the mirror is +3

Answer 1

Since m=3

The image formed is enlarged.

Now m= -v/u

Lets say that v=x & u=-y

Therefore m=-(x)/-y

By this we know that x=v

Shuold be +ve

So image is virtual and erect
