Best ResponseYou've already chosen the best response.0Using this equation: \[E_{incident photon}=E_{binding}+E_{scattered electron}\] And knowing: \[E_{incident}=h*c/\lambda\] \[E_{scattered}=1/2*m*v^2\] \[E_{binding}=K*(1/n^2)\] Being K=R*c*h (Rydberg constant, speed of light and Planck’s constant respectivily) Then you can get the velocity substituting.
