### Quiz 2

**Sat Apr 21, 2018 11:37 am**Hi!

For quiz 2 if it asks us for example to calculate the frequency of light emitted by an electron that goes from n=4 to n=2 can I use the Rydberg equation:

frequency = R [(1/n1^1) - (1/n2^1)]

or should I go through these calculations:

delta E = E(final) - E(initial) = E2-E4= (-1/4*h*R) + (1/16*h*R) and then find the frequency by doing frequency=delta E/h

Thank you so much!
