2
Q
Equation using λ
A
v=f λ
3
Q
Work Function and threshold Frequency Equation
A
Eo=hfo
4
Q
Number for Planks constant
A
6.63x10⁻³⁴ Jm/s
5
Q
Work Function
A
The minimum energy required for an electron to undergo photoemission
6
Q
Threshold Frequency
A
The frequency of a photon with energy equal to the work function
7
Q
What happens when the energy of the photon(E) is greater than the work function(Eo)
A
The extra energy is turned into kinetic energy
8
Q
Equation to find extra kinetic energy
A
Ek=E-Eo
Or
Ek = hf - hfo
