Question

A ray diagram is shown.

A tree acts as the object further than 2 F away from a biconvex lens. The distance between 2 F and the object is labeled W. The distance between F and 2 F is labeled X. There I a light ray parallel to the principal axis is bent through F on the image side of the lens. There is a ray straight through the center of the lens. The rays intersect a point below the principle axis between F and 2 F on the image side of the lens and is closer to the principal axis than the object is tall. The intersect point is labeled Z and the distance between F and 2 F on the image side of the lens is labeled Y.
Which letter represents the location of the image produced by the lens?

W
X
Y
Z

Answer 1

Z

The rays converge at point Z (between F and 2F on the image side), so Z is the real, inverted, reduced image of the tree.
