Which of the following series spectrum of hydrogen atom lies in ultraviolet region?

Step-by-step solution

The wavelength of the spectral lines in the hydrogen atom is given by the Rydberg formula: 1 = R ( 1 n₁^2 - 1 n₂^2 ) , where n₁ is the lower energy level and n₂ is the higher energy level. For the Lyman series, n₁ = 1 and n₂ = 2, 3, 4, . The transitions to the ground state ( n₁ = 1 ) involve large energy differences, which correspond to the ultraviolet region of the electromagnetic spectrum. For the Balmer series, n₁ = 2 , which lies in the visible region. For the Paschen series, n₁ = 3 , which lies in the infrared
