The wavelength of `H_(alpha)` line of Balmer series is `6500 Å`. What is the wavelength of `H_(beta)` line of Balmer series?

Explanation

To find the wavelength of the H_beta line of the Balmer series, we can follow these steps:

### Step-by-Step Solution

1. **Understand the Balmer Series**: The Balmer series corresponds to transitions of electrons in a hydrogen atom from higher energy levels (n_initial) to the second energy level (n_final = 2). The H_alpha line corresponds to the transition from n = 3 to n = 2, and the H_beta line corresponds to the transition from n = 4 to n = 2.

2. **Given Information**: We are given that the wavelength of the H_alpha line (λ_alpha) is 6500 Å.
