Questions and Answers

What is the Balmer series associated with?

Visible region of the atomic spectrum of hydrogen (correct)

X-ray spectrum of hydrogen

Ultraviolet spectrum of hydrogen

Infrared spectrum of hydrogen

Which formula represents the visible lines of the hydrogen spectrum in the Balmer series?

$ar{v} = R \left( \frac{1}{4^{2}} - \frac{1}{n^{2}} \right)$

$ar{v} = R \left( \frac{1}{2^{2}} - \frac{1}{n^{2}} \right)$ (correct)

$ar{v} = R \left( \frac{1}{3^{2}} - \frac{1}{n^{2}} \right)$

$ar{v} = R \left( \frac{1}{1^{2}} - \frac{1}{n^{2}} \right)$

Study Notes

Balmer Series

The series of spectral lines in the visible region of hydrogen's atomic spectrum is called the Balmer series.

Hydrogen Spectrum Formula

The visible lines in the hydrogen spectrum follow a specific formula:
- ν = R ( 1/2² - 1/n²)
- where:
  - ν represents frequency
  - R is the Rydberg constant
  - n is an integer greater than 2 (n = 3, 4, 5...)
