An object is placed 20cm from a convex lens. the focal length of lens is 10cm. By means of a ray diagram, find the distance between the lens and the image. Use a scale of 1cm:5cm
I got the distance as 19cm but my friend got 24cm. However, we used different measurements for height of object since question did not specify. Is this wrong?
diff height shouldn't matter.
check your textbook for object 2 focal length away from lens
