Question

bodies
An object is placed at a distance of 12 em in
front of a concave mirror. It forms a real image
Pour times larger than the object. Calculate the
distance of the image from the mirror​

Answer 1

Explanation:

Given

object distance (u)= -12

linear magnification = -4 (the image is real)

Now,

we know that m= -v/u

-4= -v/-12

v= -48
