Find the principle quantum number of the electon , having the de Broglie waveliength in an orbit of hydrogen atom is ` 10^(-9) m`

Explanation

To find the principal quantum number of an electron in a hydrogen atom with a de Broglie wavelength of \(10^{-9} \, m\), we can follow these steps:

### Step 1: Understand the de Broglie Wavelength Formula
The de Broglie wavelength \(\lambda\) is given by the formula:
\[ \lambda = \frac{h}{p} \]
where \(h\) is Planck's constant and \(p\) is the momentum of the electron.
