* Develop graphical and mathematical representations that describe the relationship between the frequency of a photon and the kinetic energy of an electron emitted through the photoelectric effect and apply those representations to qualitatively and quantitatively describe how changing the frequency or intensity of light affect the current produced in the photoelectric effect. (PII.9.3)

* Develop graphical and mathematical representations that describe the relationship between the frequency of a mechanical wave and the wavelength of the wave and apply those representations to qualitatively and quantitatively describe how changing the frequency of a mechanical wave affects the wavelength and vice versa. (PI.7.3)

* The student is able to support the photon model of radiant energy with evidence provided by the photoelectric effect. [SP 6.4] (AP P2 LO 6.F.3.1)
