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

Explanation

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

### Step 1: Convert Energy from Electron Volts to Joules
The energy given is in electron volts, and we need to convert it to joules using the conversion factor:
\[ 1 \text{ eV} = 1.602 \times 10^{-19} \text{ J} \]
So, for 5 eV:
