An electron in a hydrogen atom relaxes to the n = 1 level, emitting light with a wavelength of 102.5 nm. What is the value of n for the level in which the electron originated? You must use the following constants for your calculation: h = 6.626×10-34 J s c = 2.9979×108 m/s En = -2.18×10-18/n2 J You may use following equation: Ephoton = 2.18×10-18 (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).
