Work energy is the amount of threshold energy to dislodge a photon from the atom. o true o false

True

Explanation:

The photoelectric effect can be classified that the photon or electron emission from the atom surface when certain amount or can say that the incident particle hit by some threshold energy to the surface.

This incident particle will change the kinetic energy change of the ejected photon.

So, by the above discussion we know that work energy is change in the kinetic energy and there is also change in kinetic energy occur in the process. So, work energy can be say that the amount of threshold energy to dislodge or eject a photon from the atom.

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
