the magnification caused by a convex lens is represented by Hi/Ho, where hi is the height of the image and ho is the height of the object. Using that ratio, show that the magnification caused by a convex lens is equal to di/do(ratio of the image distance to the object distance.

From similar triangles:

Hi/di =Ho/do

=> Hi/Ho=di/do =M

fairly simple

M=hi/ho

also M=-di/do

therefore

M=hi/ho

-di/do=hi/ho

hi/ho=hi/ho

error:

fairly simple

M=hi/ho

also M=-di/do

therefore

M=hi/ho

-di/do=hi/ho

hi/ho=-di/do
