The first excited state is -13.6Ev/4= -3.4eV is where the Balmer lines start due to the n=2 is the point after the ground state. Also you excite the atom through collisions to bump one from one state to another. Would I use E = q*V and just subtract the first state from the 2nd? Such as...

I chose 2 because that is where the Balmer lines start so that is what I assumed I must use. If that is wrong may you elaborate on where I should begin at?

Homework Statement -A beam of electrons bombards a sample of hydrogen in its ground state. a) Through what minimum potental difference must the electrons be accelerated if only one line of the Balmer's series can be observed? Homework Equations V= h^2/2meλ^2 (V=potential difference)...

At a certain time a particle had a speed of 11 m/s in the positive x direction, and 1.3 s later its speed was 78 m/s in the opposite direction. What was the average acceleration of the particle during this 1.3 s interval? Homework Equations I have Vi=11m/s, Vf=78m/s and t=1.3 m/s The...
