Explanation Formula used: Write the expression for wavelength in hydrogen. λ = 91.1 1 n 1 2 − 1 n 2 2 nm (1) Here, n 1 is the final state. n 2 is the initial state. Write the expression for wavelength in ionized helium. 1 λ = R Z 2 ( 1 n 1 2 − 1 n 2 2 ) (2) Here, R is the Rydberg constant with value 1.097 × 10 7 m − 1 . Z is the atomic number. Explanation: Wavelength corresponding to the transition from 3 to 2 is, Substitute 2 for n 1 and 3 for n 2 in equation (1), λ = 91.1 1 2 2 − 1 3 2 nm = 91.1 1 4 − 1 9 nm = 91.1 5 36 nm = 655 .92 nm By cross checking the options, the states given in option B yields the same wavelength as in hydrogen atom, that is, Substitute 1.097 × 10 7 m − 1 for R , 2 (atomic number of helium) for Z , 4 for n 1 and 6 for n 2 in equation (2), 1 λ = ( 1
