Problem A15
Can someone help me solve problem A15? I've been stuck on it for about 20 minutes. I tried using the equation deltaE=-hR(1/finialn^2---1/initialn^2). Then it didn't work so I used v=R(1/finialn^2---1/initialn^2) thats shown in the book. I understand n initial is 1 because Lyman but when I work the problems out I can't seem to get the correct answer. Using the books equation I get 2.914x10^15=(3.29x10^15)(1/finialn^2----1). After this I can't get the answer as n final equals 3.

Re: Problem A15
You got the correct wavelength, however, you just switched n1 and n2 in the equation. The equation should be: wavelength = Rydberg constant *((
) - (
)). If you use this, you should get the correct answer of
= 3.

Re: Problem A15
Another equation that can be used is En= -hR/n^2. Use this equation with both n values and then subtract them from each other to get the answer.
