Part D $-$

Jump$-$DOWN:

The electron in Part A $($n $=4)$ can make a transition to lower energy states $($jump$-$down$),$ in which it must emit energy to the outside. If the electron emits $0\mathrm{.}6611$ eVeV of energy, what is its final energy?

Express your answer numerically in electron volts. Keep $3$ or $4$ digits after the decimal point.
