Photoelectric Effects and deBroglie Equation: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Photoelectric Effects and deBroglie Equation. Understanding the underlying formula is key to arriving at the correct answer below:

The momentum of a photon is given by $p = \frac{h}{\lambda}$. Since $c = \nu \lambda$, we can write $\lambda = \frac{c}{\nu}$. Substituting this into the momentum equation gives $p = \frac{h\nu}{c}$.
