Question 188 of 200

Photoelectrons are ejected from a metal when light of frequency vv falls on it. Pick out the wrong statement from the following.

Show answer and solution

Answer: (C) The maximum energy of the photoelectrons is hu.

According to photo-electric equation : K.Emax⁡=hv−hv0\mathrm{K} . \mathrm{E}_{\max }=\mathrm{h} v-\mathrm{h} v_0 (Work function) Some sort of energy is used in ejecting the photoelectrons.
