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:

To convert energy from Joules to electron-volts (eV), divide by the elementary charge $e = 1.6 \times 10^{-19} C$. Energy in eV $= \frac{10^{-20}}{1.6 \times 10^{-19}} = \frac{0.1}{1.6} = 0.0625 eV \approx 0.06 eV$.
