Photons of frequency v fall on a metal surface for which the threshold frequency is v0. Then,
- All ejected electrons have the same kinetic energy h(v – v0)
- the ejected electrons have a distribution of kinetic energy from zero to h(v – v0)
- the most energetic electrons have kinetic energy hv
- the average kinetic energy of ejected electrons is hv0.
Answer
(B) the ejected electrons have a distribution of kinetic energy from zero to h( v – v 0 )
