Question

What will be the wavelength emitted radiation when an electron jumps from third orbit to a first orbit in a hydrogen atom?

Answer 1

Explanation:

It needs to gain (-3.4) - (-13.6) = 10.2 eV of energy to make it up to the second energy level. The electron can gain the energy it needs by absorbing light. If the electron jumps from the second energy level down to the first energy level, it must give off some energy by emitting light
