A photon of frequency `5 xx 10^(14)Hz` is incident on the surface of a metal. If the photoelectric thresh-old frequency for the metal is `3 xx 10^(14)Hz`, Calculate the following
Photoelectric work function in eV

Explanation

To calculate the photoelectric work function in electron volts (eV) for the given metal, we will follow these steps:

### Step 1: Identify the given values
- Frequency of the incident photon, \( \nu = 5 \times 10^{14} \, \text{Hz} \)
- Threshold frequency of the metal, \( \nu_0 = 3 \times 10^{14} \, \text{Hz} \)

### Step 2: Use the formula for the work function
The work function \( \phi \) can be calculated using the formula:
