Ratio of the wavelength of first line of Lyman series and first line of Balmer series is

Explanation

To find the ratio of the wavelengths of the first line of the Lyman series and the first line of the Balmer series, we can follow these steps:

### Step 1: Identify the transitions for the Lyman and Balmer series
- The first line of the Lyman series corresponds to the transition from n=2 to n=1.
- The first line of the Balmer series corresponds to the transition from n=3 to n=2.

### Step 2: Use the formula for wavelength in hydrogen spectrum
The formula for the wavelength of light emitted during a transition in a hydrogen atom is given by:
