Required information

An electron confined to a one$-$dimensional box has a ground$-$state energy of $34\mathrm{.}2$ eV $.$

If the box were somehow made twice as long, how would the photon's energy change for the same transition $($first excited state to ground state$)?$

Multiple Choice

$$ increase the energy to three times as much as before

$$ increase the energy to two times as much as before

$$ reduce the energy to one half as much as before

$$ reduce the energy to one fourth as much as before

$$ reduce the energy to one third as much as before
