Answer:
31.8 Joules is the the energy of the photon of light that was absorbed.
Explanation:
Initially the electron is present at energy level equal to -50.3 Joules and on absorbing an energy it jumps to energy level which has energy of -18.5 Joules.
(Initial)
(Final)
ΔE , here is also the energy of the photon absorbed by an electron before transition.
31.8 Joules is the the energy of the photon of light that was absorbed.
