The Rydberg equation, with n1=1, predicts an ultraviolet series of spectral lines of atomic hydrogen. Which of the following wavelengths is not predicted by the equation: 1/ = (1.097 x 10(7) m - 1) x (1/n1(2)-1/n2(2)
a)182 nm
b)103 nm
c)97 nm
d) 95 nm
e) 91 nm
I was thinking 182 nm, is this correct?

I think you need to do the work and not guess.
1/wavelength = 1.097 x 10^7[1-(1/n)] where n = 2, 3, 4, 5, 6 for the five answers. One doesn't fit. Note: Plug in 2 for n and you get 182 nm.
