Calculate the frequency and wavelength of photon with energy `3.98 xx 10^(-15)J`

Explanation

To solve the problem of calculating the frequency and wavelength of a photon with energy \(3.98 \times 10^{-15} \, \text{J}\), we will follow these steps:

### Step 1: Calculate the Frequency
We will use Planck's equation which relates energy (E) to frequency (ν):

\[ E = h \nu \]
