 Let the hydrogen atoms be excited to nth energy level. 12.3=13.6112-1n2⇒12.3=13.6-13.6n2⇒13.6n2=13.6-12.3=1.3⇒n2=13.61.3⇒n≈3 The formula for calculating the wavelength of Lyman series is given below: 1λ=R1-1n2 For the second member of Lyman series: n = 3 ∴1λ=R1-132⇒1λ=1.09737×10789⇒λ=1025 A∘ The formula for calculating the wavelength of Balmer series is given below: 1λ=R14-1n2 For second member of Balmer series: n = 4 ∴1λ=R14-142⇒1λ=1.09737×107316⇒λ=4861 A∘
