Question

Radiation coming from transition n = 2 to n = 1 of hydrogen atoms fall of He⁺
ions in n = 1 and n = 2 states. The possible. Transition of helium ions as they absorb energy from the radiation is:
(A) n = 2 → n = 4 (B) n = 2 → n = 5
(C) n = 2 → n = 3 (D) n = 1 → n = 4

Answer 1

Answer:

A. n = 2 to n = 4

just multiply z2/n2
