Which, of the following is true of the Balmer series of the hydrogen spectrum?
a. The series is in the visible region.
b. The entire series falls in the ultraviolet region
c. The entire series falls in the infrared region
d. The series is partly in the visible region and partly in the infrared region
- A b
- B a
- C c
- D d
Answer & Solution
Correct Answer
(B) a
Step-by-step Solution
Detailed explanation
The wavelength of spectral lines in the hydrogen spectrum is given by the Rydberg formula: \(\dfrac{1}{\lambda} = R \left( \dfrac{1}{n_1^2} - \dfrac{1}{n_2^2} \right)\), where \(R\) is the Rydberg constant, \(n_1\) is the lower energy level, and \(n_2\) is the higher energy…
