Solution

The correct option is B Completely disappears
Answer is A.
Incident photon involved in the photoelectric effect may completely disappears or comes out with out change in frequency.
Case I : When frequency of light is less than threshold frequency than no ejection of electrons takes place so, photon comes out with same
frequency.
Case II : When frequency of light is more than threshold frequency, then workfunction energy is consumed into the ejection of electrons and rest energy is consumed into kinetic energy of electron. So, photon completely disappears.

In practical experiments of photo electric effect the total number of photo electrons coming out is less than 1% of the total number of photons falling on the plate.

Threshold frequency for a metal is $10^{15} H z$ . Light of $λ = 4000 \circ A$ falls on its surface. Which of the following statements is correct

In an experiment on photo electric effect, light of wavelength 400 nm is incident on a cesium plate at the rate of 5.0 W. The potential of the collector plate is made sufficiently positive with respect to the emitter so that the current reaches its saturation value. Assuming that on the average one out of every $10^{6}$ photons is able to eject a photo electron, find the photo current in the circuit.
