Calculate the frequency of the light emitted when an electron in a hydrogen atom makes each transitions.?
n=4 => n=3 ? v = ________________ s^1
n=5 => n=1 ?
n=5 => n=4 ?
n=6 => n=5 ?
I got the first one correct (1.6*10^14) but the rest i am getting wrong. Can anyone help me solve the last 3 questions?

1/wavelength = R(1/1^2  1/5^2)
Then c = f*w and solve for f.
