JEE Main Chemistry question

An electron from one Bohr stationary orbit can go to the next higher orbit **[UP SEE 2008]**

(A)By emission of radiant energy
(B)By absorption of any electromagnetic radiation
(C)By absorption of electromagnetic radiation of particular frequencyCorrect
(D)Without emission or absorption of electromagnetic radiation

Answer: (C)

Solution

Moving to a higher orbit requires the electron to gain exactly the energy difference between the two levels, which it can only do by absorbing a photon
