8. An exited hydrogen atom emits a photon having a wavelength of 388.9049 nm and the electron relaxes down to the n=2 level. What was the initial higher energy level of the electron? - hc 388.9049x10 nm -9 = -2.184x102 (12)
4. An atom emits a photon with a wavelength of 872 nm when its electron moves from the n = 5 energy level to the n = 4 energy level. From this fact, what can you can conclude? (Hint: drawing a diagram may be helpful) (A) This atom must emit lower energy light than the 872 nm light when moving from the n= 5 energy level to the n= 1 energy level (B) This atom's electron can transition from the...
A certain atom emits a photon of wavelength 520 nm (1 nm = 10-9 m) when an electron jumps from a higher allowed orbit to a lower orbit. What is the frequency of the photon? What is the photon energy in Joules? What color in the visible light spectrum does it correspond to?
