Calculate the wavelength, wave number and frequency of photon having its energy 5 electron volt.

Explanation

To solve the question of calculating the wavelength, wave number, and frequency of a photon with an energy of 5 electron volts (eV), we will follow these steps:

### Step 1: Convert Energy from Electron Volts to Joules
We know that:
\[ 1 \text{ eV} = 1.6 \times 10^{-19} \text{ Joules} \]

Given energy \( E = 5 \text{ eV} \):
\[
