 The wavelength of an electron for the transition from  a state n1 to n2 is   $\frac{9}{8R}$ which of the following wavelength is possible for a transition from n2 to n1


A) $\frac{16}{15R}$

B) $\frac{4}{3R}$

C) $\frac{9}{8R}$

D) $\frac{36}{5R}$

Answer:

Option C

Explanation:

Energy released  in transition from state n1 to n2  is equal to the energy absorbed in transition from state n2 to n1
