Calculate the wavelength, wave number and frequency of photon having an energy to three electron volt.
`(h=6.62xx10^(-27) erg-sec)`.

Explanation

To solve the problem of calculating the wavelength, wave number, and frequency of a photon with an energy of 3 electron volts (eV), we will follow these steps:

### Step 1: Convert Energy from Electron Volts to Ergs
The energy \( E \) is given as 3 eV. We need to convert this to ergs using the conversion factor:
\[ 1 \text{ eV} = 1.602 \times 10^{-12} \text{ erg} \]

So, we calculate:
\[
