What is the wavelength of light emitted when the electron in a hydrogen atom undergoes transition from the energy level with `n=4` to the energy level with `n=1` ?

Explanation

To find the wavelength of light emitted when an electron in a hydrogen atom transitions from the energy level \( n=4 \) to \( n=1 \), we can use the Rydberg formula for the wavelength of emitted light. Here’s a step-by-step solution:

### Step 1: Identify the Rydberg Formula
The Rydberg formula for the wavelength (\( \lambda \)) of light emitted during an electron transition is given by:

\[ \frac{1}{\lambda} = R_H \left( \frac{1}{n_1^2} - \frac{1}{n_2^2} \right) \]
