All of the following statements about real and virtual images are true except which one?

• Real images can be projected onto a screen; virtual images cannot.

• Both converging and diverging lenses form real images.

• A real image is formed when light rays intersect.

• Virtual images form at a point from which light rays appear to come but do not actually come.

The size and location of an image formed by a converging lens depends on the

• location of the object in relation to the lens.

• location of the image in relation to the lens.

• location of the observer in relation to the lens.
