Question
A photo sensitive metallic surface has work function hv0. If photons of energy 2hv0 fall on this surface, the electrons come out maximum velocity of 4 × 106m/s. When the photon energy is increased to 5 hv0. then maximum velocity of photo electrons will be : -
Options
A.2 × 106 m/s
B.2 × 107 m/s
C.8 × 105 m/s
D.8 × 106 m/s
⇒ v2 = 8 × 106 ms-1.More Nuclear Physics and Radioactivity Questions
