Question 2
A hydrogen atom is excited to the n = 10 stated. It then decays to the n = 4 state by emitting a photon which is detected in a photographic plate. What is the frequency of the detected photon?
The lowest level energy state of hydrogen is -13.6 eV. (h = 6.626 10-34 J s,
1 eV = 1.60 10-19 J)
A) 3.46 1014 Hz
B) 0.865 1014 Hz
C) 1.27 1014 Hz
D) 4.05 1014 Hz
E) 1.73 1014 Hz
