Question

how to calculate the wavenumber of photon? like we have n=5 and n=2

Answer 1

rydberg formula

Answer 2

I ASKED HOW??? TELL ME THE FORMULA AND ALSO WE HAVE TO APPLY THE SAME FORMULA FOR ALL THE QUESTIONS??

Answer 3

wow relax

Answer 4

if it's for a hydrogen atom, use this

Answer 5

ok thx but Can u plz explain this by this question like n=5 and=2?

Answer 6

an electron is transiting (falling back down towards the nucleus) and is emitting a photon of energy proportional to the transit.

with the formulae i posted, substitute in nf = final ; and ni = initial

so ni=5, and nf=2

then solve algebraically

Answer 7

R, rydberg constant, is 1.097x10^5 /cm

Answer 8

this is only if it's for a hydrogen atom, it all little different if it's for another element
