Question

What does this mean :
when the frequency of incident radiation is doubled, the kinetic energy of photo electron is more than doubled because work function remains constant. can someone please explain this? ​

Answer 1

Answer:

KE = energy of incoming photon- work function. Now work function is constant for every individual, so if we double the energy of electron whole of the increased energy while be a addition to KE of electron.

So, the answer is option (C).
