The correct answer is A; or 9.38x10^-3.
Explanation:
f=3.20x10^10 c= 3.00x10^8
Once you divide those by each other, your answer is 9.83x10^-3
Hope this helps!! :)
<span>Energy is absorbed and then released to form an emission line.
When electrons absorb energy they increase there energy level. This is only temporary and the excited electron then relaxes back down to its original energy level releasing energy.
The energy is released in form of EM radiation of a specific frequency depending on the element and how many energy levels the electron relaxes.
This forms an emission line.</span><span />
