1
Q
Threshold frequency
A
f = Φ/h
where Φ = work function (J)
and h = Planck’s constant
2
Q
What is Φ?
A
The work function of a metal - it is the amount of energy required to remove an electron from the surface of the metal
3
Q

A
Ek = hf - Φ
4
Q
Relationship between probability and resultant phasor
A
Prob. ∝ (Resultant phasor)²
