When these photons strike the surface, they knock electrons off it; we call these photoelectrons.

当这些子击表面时，它们会把子；们之子。

The electrons which are emitted during such a process are called photoelectrons.

在这个过程中发射的子子。

Look at this graph, you can see that the number of photoelectrons emitted increases as the intensity of the incident light increases.

看这张图，你可以看到，随着入射强度的增加，发射的子数量也在增加。
