Question #65037

Answer 1

I would say: Cannot Determine

Explanation:

We need to consider that the emission of electrons (Photoelectric Effect) will depends upon FREQUENCY, so, the higher the frequency the higher the energy carried by the photons of light interacting with the metal surface and the possibility to emit electrons.
Let us have a look at the EM spectrum of light:

As you can see Red has a lower frequency than Blue and Green and we would be induced to think that Green, having a higher frequency, will produce photoelectrons...
BUT:
We have an additional factor; the material Work Function!
The electrons in the material need a minimum of energy to be emitted because the molecular structure of the material and the way they are bound.

The electrons can be strongly bound inside the material and so in need of more energy than the one carried by the photons of light to be dislodged.

So the electron in the metal, to be emitted, will need at least a certain amount of minimum energy (Work Function) to be able to get free:

`"Energy of incoming photon"="at least"="Work Function"`

Here we cannot evaluate this minimum energy and we do not know whether Green light will able to provide it or not.
…I think…
