Sapling 6

so I was able to figure out the spectral line and the wavelength for n=1 and n=7, but the second part says it's wrong. So for the second one I'd use n=6 and n=7 and use v= (3.29x10^15)((1/6^2)-(1/7^2))

That seems right to me. Maybe just double check to make sure you are converting to wavelength correctly by using wavelength = c/v, and then making sure you convert correctly to nanometers. Hope this helps!

If you're still having issues, I know sapling has some pretty good AI and the tips they give you are relevant to the answers you put.

Your equation looks right, so I would make sure you put everything into your calculator right. I would also make sure you converted the frequency into wavelength right using lambda = c/f. Then change the wavelength into nanometers.
