JEE MainPhysicsAtoms and NucleiMCQ+4 / −1
The electron in a hydrogen atom first jumps from the third excited state to the second excited state and subsequently to the first excited state. The ratio of the respective wavelengths, λ1λ2{{{\lambda _1}} \over {{\lambda _2}}}λ2​λ1​​, of the photons emitted in this process is :
  1. A
    225{{22} \over 5}522​
  2. B
    75{7 \over 5}57​
