🤓 Based on our data, we think this question is relevant for Professor Campbell's class at Tufts University.

We’re being asked to calculate for the maximum possible kinetic energy of the emitted electron from a sodium metal. When photons with enough energy hit the surface of a metal, electrons are emitted. This phenomenon is known as the Photoelectric Effect.

**Total energy (****ΔE)** in photoelectric effect can be calculated using the following equation:

$\overline{){\mathbf{\u2206}}{\mathit{E}}{\mathbf{=}}{{\mathit{E}}}_{\mathbf{w}\mathbf{o}\mathbf{r}\mathbf{k}\mathbf{}\mathbf{f}\mathbf{u}\mathbf{n}\mathbf{c}\mathbf{t}\mathbf{i}\mathbf{o}\mathbf{n}}{\mathbf{+}}{{\mathit{E}}}_{\mathbf{k}\mathbf{i}\mathbf{n}\mathbf{e}\mathbf{t}\mathbf{i}\mathbf{c}\mathbf{}\mathbf{e}\mathbf{n}\mathbf{e}\mathbf{r}\mathbf{g}\mathbf{y}}}$

**Where:**

• **Δ****E **is* the** total energy or the energy of the light/photon/radiation* and can be calculated using the equation:

$\overline{){\mathbf{\u2206}}{\mathbf{E}}{\mathbf{=}}{\mathbf{h\nu}}}$

E_{total energy} = J

h = Planck’s constant = 6.626x10^{-34} J∙s

ν = frequency = Hz or s^{-1}

• **E _{work function} **is

Sodium metal requires a photon with a minimum energy of 4.41 x 10 ^{-19} J to emit electrons. (c) If sodium is irradiated with light of 439 nm, what is the maximum possible kinetic energy of the emitted electrons?
