Default Physics Help

Hi I would appreciate it if you solved this question!


The light intensity incident on a metallic surface
produces photoeletrons with a maximum
kinetic energy of 2.23 eV.
If the light intensity is doubled, what is
the maximum kinetic energy of the photoeletrons?
Answer in units of eV.
