Photoelectric Effects and deBroglie Equation: Practice Problem & Solution

The number of photo electrons emitted for light of a frequency $\nu$ (higher than the threshold frequency $\nu_0$) is proportional to: (2009)
Threshold frequency ($\nu_0$)
Intensity of light
Frequency of light ($\nu$)
$\nu - \nu_0$

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:

According to the laws of photoelectric emission, the number of photoelectrons emitted per second (photoelectric current) is directly proportional to the intensity of incident light, provided the frequency is above the threshold frequency.
