Question

In which transition, one quantum of energy is
emmited :
(1) n = 4 → n = 2
(2) n = 3 → n = 1
(3) n = 4 - n = 10
(4) All of them ​

Answer 1

Answer:

(3) n = 4 - n = 10

Explanation:

In all the three transitions n=4→n=2, n=3→n=1 and n=4→n=1, one quantum of energy is emitted. Whenever an electron jumps from higher energy level to lower energy level, a quantum of energy is emitted.
