the order of energy levels (n) in the

[OishiBhattacharya2K]

In the equation v = R((1/n1^2)-(1/n2^2)), is it safe to assume that n1 is the final energy level and n2 is the initial energy level, almost like saying v = R((1/nfinal^2)-(1/ninitial^2)), or does it depend on the context of the question?

Hi!

It doesn't exactly matter, but depending on context you might want to change the sign of the final answer. If it goes from a higher energy level to a lower one, then the delta E value will be negative, and if it goes from a lower energy level to a higher one, then delta E is positive.

Hope this helps! ^^

It should always be nfinal - ninitial - so I believe that's a safe assumption.

Hi!
In that case yes you can assume that, but to be safe when doing problems always look at the context of the problem and make sure its n(final)-n(initial

I don't believe it depends.
