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

Explanation

To calculate the frequency and wavelength of a photon with energy \( E = 3.98 \times 10^{-15} \, \text{J} \), we can follow these steps:

### Step 1: Use the energy-wavelength relationship
The energy of a photon is related to its wavelength by the equation:
\[ E = \frac{hc}{\lambda} \]
where:
