Question:medium

If $v_0$ is threshold frequency and $v$ is incident frequency, velocity of photoelectrons is:

Show Hint

Photoelectron velocity depends on excess frequency above threshold.

  • $v=\sqrt{\frac{2h}{m}(v-v_0)}$
  • $v=\sqrt{\frac{2h}{m}(v_0-v)}$
  • $v=\sqrt{\frac{m}{2h}(v-v_0)}$
  • $v=\sqrt{\frac{m}{2hc}(v_0-v)}$
