A difference of 2.3 eV separates two energy levels in an atom. What is the frequency of radiation emitted when the atom makes a transition from the upper level to the lower level?

Explanation

Separation of two energy levels in an atom,
`DeltaE=2.3eV`
`=2.3xx1.6xx10^(-19)`
`implies3.68xx10^(-19)J`
As, `DeltaA=hv`
where, y=frequency of radiation emitted when the atom is transmitted from upper level to lower level.
`impliesv=(DeltaE)/(h)=(3.68xx10^(-19))/(6.63xx10^(-34))`
`=5.6xx10^(14)Hz`
Hence, frequency of radiation is `5.6xx10^(14)Hz.`
