Energy absorption

Vedclass · Answer

(A) The energy levels of an atom are quantized,where $K$ shell $(n=1)$ is the lowest energy level,followed by $L$ shell $(n=2)$,$M$ shell $(n=3)$,and so on.When an electron transitions from a lower energy shell (like $L$,$n=2$) to a higher energy shell (like $M$,$n=3$),it must gain energy to overcome the energy difference between the two states.Therefore,this process is accompanied by the absorption of energy.

When an electron moves from $L$-shell to $M$-shell,then it will be accompanied by :
