The wavelength of a photon needed to remove a proton from a nucleus which is bound to the nucleus with 1MeV energy is nearly

Options

A. 1.2 nm
B. `1.2xx10^(-3)` nm
C. `1.2xx10^(-6)`nm
D. `1.2xx10` nm

Explanation

To find the wavelength of a photon needed to remove a proton from a nucleus that is bound with 1 MeV of energy, we can follow these steps:

### Step 1: Convert the energy from MeV to Joules
The energy of the proton is given as 1 MeV. We need to convert this energy into Joules.

\[ 1 \text{ MeV} = 1 \times 10^6 \text{ eV} \]
