What is the height of the image? Round your answer to three significant figures.
cm
Intro

Explanation:

We have,

Height of object is 5 cm

Object distance from a convex lens is 18 cm

Focal length of convex lens is 10 cm

i.e. h = 5 cm

u = -18 cm

f = +10 cm

Let v is distance of the image from the lens. Using lens formula :

The magnification of lens is :

, h' is height of the image

h' = -5.00 cm (in three significant figures)
