The incident photon involved in the photo-electric effect experiment
The incident photon involved in the photo-electric effect experiment \( \nu>\nu_{o} \)
- A. Completely disappears
- B. Comes out with increased frequency
- C. comes out with a decreased frequency
- D. Comes out with out change in frequency
Step-by-step solution
In the photoelectric effect, when a photon with frequency greater than the threshold frequency (ν > ν_o) strikes a metal surface, it is absorbed entirely by an electron. The photon's energy is transferred to the electron, which is then emitted. The photon ceases to exist after this process, so it completely disappears.
