Missing Atomic Spectral Lines
A gas of identical atoms is excited by an electrical discharge. An analysis of the resulting emission spectrum reveals that certain expected spectral lines are absent. Which of the following best explains this observation?
A
The missing wavelengths were absorbed by the atmosphere
B
The atoms did not receive sufficient energy to emit all lines
C
The detector was not sensitive to those wavelengths
D
Some transitions are forbidden by quantum selection rules
