Using Bohr's model , calculate the wavelength of the radiation emitted when an electron in a hydrogen atom make a transition from the fourth energy level to the second energy level

Explanation

To solve the problem of calculating the wavelength of radiation emitted when an electron in a hydrogen atom transitions from the fourth energy level to the second energy level using Bohr's model, we can follow these steps:

### Step 1: Identify the Energy Levels
We need to identify the initial and final energy levels of the electron transition.
- The initial energy level (n2) is 4.
- The final energy level (n1) is 2.

### Step 2: Use the Bohr Model Energy Formula
