What is the wavelength of the line in the Balmer series of hydrogen that is comprised of transitions from the n = 5 to the n = 2 level? (R = 1.097 × 10⁷ m−¹ and 1 nm = 10−⁹ m) A)304 nm B)434 nm C)476 nm D)95 nm E)333 nm

Question

Quizplus · Accepted Answer

The wavelength of the line in the Balmer series for a transition from n = 5 to n = 2 can be calculated using the Rydberg formula: $ \frac{1}{\lambda} = R \left( \frac{1}{2^2} - \frac{1}{5^2} \right) $. Plugging in the given value for R and solving for $ \lambda $ gives a wavelength close to 434 nm.
