question mark

         When Cesium is illuminated with light of wavelength 546 nm, the maximum speed of the electron emitted is 3.63x10^5 m/s. What is the maximum speed of the emitted electrons when the metal is illuminated by light of wavelength 450 nm?


        A hydrogen atom in the n=4 state makes a transition to the ground state, emitting one photon. Calculate the wavelength of the emitted photon and the recoil velocity of the atom.
