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 number of emitted photoelectrons per second is directly proportional to the intensity of the incident radiation, so it becomes 2N. However, the maximum kinetic energy depends only on the frequency of the incident radiation and the material's work function, so it remains T.
