Question
Photons of light with an energy of 97 nm are being directed through a chamber of hydrogen gas atoms. The gas atoms began in their ground state (ni=1).
Which of the following statements is true?
a) These photons are in the ultraviolet and quite energetic. They will produce the following electronic transitions:
ni=1, nf=2;
ni=1, nf=3;
ni=1, nf=4;
ni=2, nf=3;
ni=2, nf=4;
b) This will result in emission of photons in the ultraviolet, visible, and infrared regions of the electromagnetic spectrum.
c) There will exactly 3 emission lines produced.
d) All of these photons will pass through the chamber. None of them will interact with the hydrogen.

Explanation / Answer
(a) is the correct statement.eiectronic transitions are produced.after interacting with these photons some move to (ni=2)
