Calculate the frequency of a photon whose energy is `3xx10^(-19)` J, Also , find its momentum.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Calculate the frequency of the photon

The energy of the photon is given by the equation:
\[ E = h \nu \]
where:
- \( E \) is the energy of the photon (in joules),
...
