参考答案:
Real images can be
projected onto a screen. In this
situation, real light rays actually focus at the position of the image, which
can be seen on the screen. But virtual
images cannot be projected onto a screen.
In this situation, no real light rays are crossing at the position of
the virtual image, and so they cannot be seen on a screen (recall a plane
mirror’s virtual image is actually behind the mirror, where no real light rays
travel). Both real images and virtual
images can be photographed. The lenses
in the camera are designed to focus either diverging or converging light rays
down onto the film (similar to a human eye, which can also focus either
diverging or converging light rays down onto our “film”).
