Binding Energy per Nucleon

Binding Energy per Nucleon is a negative energy or a debt of energy. This is the amount of energy it would take to liberate a nucleon from the nucleus. This energy was originally radiated off when the nucleus formed.

The energy radiated off, the Binding energy, is lost energy and comes from mass that is lost by the nucleons. Mass per Nucleon shows what is left over once a bound nucleon has radiated away some of its mass.

Photoelectric Effect

The concept of the Photoelectric Effect was introduced and how light modeled as a particle can explain this, while light modeled as a wave cannot.

The above video explains the Photoelectric Effect using a PhET application which I encourage you to use and experiment with.
This can be found at:

Planck's Constant h = 6.63 x 10-34 Js

Energy of a Photon E = hf

Threshold Frequency fo , the frequency of incident photons that have an energy equal to the work function of the metal

Work Function Ï† = energy required to free an electron from a specific metal (J)

Maximum Kinetic EnergyEk,  of a freed electron by an incident photon:
Ek = hf - φ
