Is incident light the same as threshold energy?

Incident light refers to the light that is shined onto a plate of metal. This light can have more or less energy than the threshold energy. The threshold energy for a plate of metal is fixed, whereas the energy of incident light can vary depending on its frequency.

Threshold energy varies per metal correct?

Threshold does vary among different metals because the work function energy varies. The work function varies due to the position of the electrons in that metal. The shape of the metal determines where and how the electrons move off the metal.
