Refer to the figure above. Assuming that all transitions between levels are possible, how many spectral lines will this atom exhibit?

1) 1
2) 2
3) 3
4) 4
5) 5

The spectral line of highest frequency will result from an electron transition from n = 3 to
6) n = 2.
7) n = 1.
8) either, if the levels are equidistant.

Question 2

The electrons that make up the current in an electric circuit move by

1) interacting with the electric field established in the circuit.
2) bumping into one another in such as way as to send pulses over long distances.

The drift speed of individual electrons making up the current is
3) very low, about a snail's pace.
4) about the speed of sound.
5) about the speed of light.
