When photons of energy $h v$ fall on an aluminium plate (of work function $E_{0}$ ), photoelectrons of maximum kinetic energy $K$ are ejected. If the frequency of radiation is doubled, the maximum kinetic energy of the ejected photoelectrons will be:NEET 2006

Options:

Answer:

Solution:

According to given situation $and \Rightarrow h v 2 h v k^{'} = E_{0} + K = E_{0} + k^{'} = k + h v$
