Question

the magnification produced by a convex lens is -2. What is the image distance if the object is placed 10cm away to the left side of the lens​

Answer 1

Answer:

The magnification produced by a lens is equal to the ratio of image distance to the object distance.

Explanation:

Object distance = x

image distance = y

so, m = y/x

m = -2(according to the question) and image distance(x) = 10cm

-2 = y/10

y = -20cm

image distance in convex lens is positive maybe so is y = 20cm ?

u calculate that! :)

hope it helps! :D
