threshold energy

[AMahadi]

what does the threshold energy represent?

[Haley Chun 4H]

the amount of energy required to remove an electron from the metal surface. ex) if the energy of the photon is less than the threshold energy, no electrons will be ejected

[Reagan Smith 1H]

Threshold energy, also called work function, is the energy needed to remove an electron from a metal surface using a light.

[Erik Buetow 1F]

Threshold energy is basically the minimum energy of the incoming photon needed to remove an electron from the metal surface.

[Megan Jung 3A]

Threshold energy is also known as the work function. It represents the amount of energy of light is needed to remove an electron from a metal's surface. This is a specific characteristic of a metal and therefore stays constant for the same material.
