A laboratory records the energy released in two transitions.
| Transition | Energy released (J) |
|---|---|
| X | 4.0 × 10-19 |
| Y | 2.0 × 10-13 |
Use h=6.63×10−34 J sh = 6.63\times10^{-34}\ \mathrm{J\,s}h=6.63×10−34 Js.
Calculate the frequency of the radiation from each transition and identify which transition is more likely to be a change in a nucleus.
