Abstract: In this chapter, we further examine the properties of the Fock or number state, |n⟩. The average photon number and average electric field of a Fock state are derived, along with their uncertainty. We show that the Fock state has the unusual property of having a precise number of photons, n, but with average electric field of zero. Although the average field is zero, there is an uncertainty or fluctuation in the field. The properties of the Fock state |0⟩, called the vacuum, are presented along with the concept of vacuum field fluctuations and their experimental consequences.
