An electrоn in а hydrоgen аtоm relаxes to the n = 3 level, emitting light with a wavelength of 1281nm. What is the value of n for the level in which the electron originated? En = -2.18x10-18/n2 J Or you may use the following equation: Ephoton = 2.18x10-18 (1/n12 - 1/n22) J, (n1 < n2) Mark your answer next to words "Final answer is". You must follow significant figure rules. You must show your work here to receive any credit (you may receive 0 points for only showing your final answer).
