Find out the wavelength of the electron orbiting in the ground state of hydrogen atoms.

Explanation

To find the wavelength of the electron orbiting in the ground state of a hydrogen atom, we can follow these steps:

### Step 1: Determine the energy of the electron in the ground state
The energy of an electron in a hydrogen atom in the ground state (n=1) is given by the formula:
\[ E = -\frac{13.6}{n^2} \text{ eV} \]
For the ground state (n=1):
...
