Homework Statement
A hydrogen electron is at its ground level when it's radiated in wave length of 94.92 nm. As a result it arrises to level a. then emission occures with frequency of 2.34*10^14 Hz and the electron falls to level b. What's the energy difference between the 2 levels
Homework Equations
E=hv, c=λv
The Attempt at a Solution
I found E1 using λ1 that's given to me, E2 using v2 given to me and substracted E2 from E1. Why isn't this way correct and you have to use rydberg's formula? whay the 2 don't give the same result? I got 1.94*10^-18 J
