Threshold level and Work Function
Threshold level and Work Function are basically the same thing right?

Re: Threshold level and Work Function
Yes they are! They are just names that are used interchangeably and are both denoted by the symbol Φ.

Yes. It's also known as the minimum amount of energy needed to remove an electron.

Re: Threshold level and Work Function
Yes, the threshold is the same as the work function. Essentially it is just the amount of energy needed to eject an electron from a piece of metal.

Re: Threshold level and Work Function
Yes! When the kinetic energy of an ejected electron is zero, then the work function must equal the energy of the photon hitting the metal surface.

Re: Threshold level and Work Function
When do we use 1/2mv2 for Ek and when do we use de broglies equation for Ek?
