4) A metal surface has a work function of 1.50 eV. If light of frequency 6.10 × 10¹4Hz falls on this surface what is the maximum speed of the emitted electrons most closely equal to? (Planck constant: 6.63 × 10-34 Js or 4.14 x 10-15 eVs). a) 6.0 x 105 m/s b) 8.0 x 105 m/s c) 6.0 x 106m/s d) 8.0 x 106m/s e) 3.0 x 108m/s
