A photon is emitted during the transition from the n=7 state to the n=1 state in the hydrgoen atom. Note: Rydberg constant: 2.18 X 10^-18 J  a) Calculate the wavelength of this photon. b) Can this photon eject an electron from cesium metal ( work function of Ca is 3.42 X 10^ -19 J) and why? What would be the speed of the electron once it is ejected (mass electron is 9.109 X 10 ^-31 Kg) ?
