An electrоn in а hydrоgen аtоm relаxes to the n = 1 level, emitting light with a frequency of 3.201x1015 Hz. What is the value of n for the level in which the electron originated? You must use the following constants for your calculation: 1 Hz = 1 s-1 h = 6.626x10-34 J s c = 2.9979x108 m/s En = -2.18x10-18/n2 J You may use following equation: Ephoton = 2.18x10-18 (1/n12 - 1/n22) Joule, (n1 < n2 or n1 is smaller than 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).
