Street Signs аre shоps аll rely оn neоn lights to cаtch attention. Different gases in discharge tubes used for the lights emit different colors when an electric current passes through them. a) Explain, in terms of electronic structure, why each gas produces its own unique emission spectrum. (4 points) b) A neon sign emits bright red-orange light with a dominant wavelength of ~ 640 nm. Calculate the energy (in joules) of a single photon of this light. ( 4 points) Use h=6.626×10−34 J⋅sh = 6.626 times 10^{-34} , J cdot s c=3.00×108 m/sc = 3.00 times 10^{8} , m/s *make sure to show all your work - giving only the answer or irrelevant work will earn a zero grade.
