1.	What is the frequency and wavelength of a photon emitted during a transition form n2=5 state N1=2 state of hydrogen atom.
Answer» The frequency is nothing but c/& as speed=frequency TIMES wavelength. THUS, Energy = Planck's constant(H)*frequency(v). According to your case, the electron is in a transition STATE from n=5 to n=2. So, the TOTAL energy during the transition is given by E(net) = E(at state 5) - E(at state 2).
