Elements is the answer to this question
I think it's something like electrons don't attract, cuz you know the saying "Opposites attract." Cause electrons are negative... Ahaha... sorry, I don't know the answer.
From the items on that particular list, the longest waves are radio waves.
Answer:
Yes I think... But the joke is it is a walk then.
Answer:
If the absorbed beam is monochromatic (one wavelength) then it excites the H atom to some state n.
When that state decays, some of the atoms may decay to state 1, others to state 2, and still others to state 3
The net energy emitted in such a case would depend on:
n -1, n - 2, n - 3 which would produce 3 different wavelengths
