Question

how does an e excites actually . dosent it seem to violate scrodinger wave equation as it excites passing a node where probability of finding an e is 0?​

Answer 1

Answer:

i understand your doubt.

actually it dosent violate scrodinger wave equation .for example , for a 2s system there is a node present and it is the characteristic feature of that state.when an e excites from 1s its state changes .in the excited state it does not have the same wave function. so in the excited it might not be passing the 0 probability area which seems to be there in the 2s state.
