A ray diagram is shown.
Masja [62]

Answer:

Z

Explanation:

The figure represented the ray diagrams produced by a convex (converging lens). The image will appear at the point where the purple ray and the orange ray meet, so at point Z.

As we see from the picture, the image will be:

- Real (because it is behind the lens, and it can be projected on a screen)

- Inverted (the image is upside down)

- Larger than the object (we can see it by noticing that the distance between the point of intersection purple-orange ray and the axis is larger than the size of the object)
