7: Equations

Question 1

Threshold frequency

Answer 1

f = Φ/h
where Φ = work function (J)
and h = Planck’s constant

Question 2

What is Φ?

Answer 2

The work function of a metal - it is the amount of energy required to remove an electron from the surface of the metal

Question 3

Maximum Kinetic Energy =

Answer 3

Ek = hf - Φ

Question 4

Relationship between probability and resultant phasor

Answer 4

Prob. ∝ (Resultant phasor)²
