When intensity of incident light increases (a) photo-current increases (b) photo-current decreases (c) kinetic energy of emitted photoelectrons increases (d) kinetic energy of emitted photoelectrons decreases

Answer: (a). Higher intensity means more photons per second, so more electrons per second: photocurrent increases. Kmax = hν - φ does not change with intensity. So the answer is (a) photo-current increases.

When intensity of incident light increases

Show answer and solution

Answer: (a)

Higher intensity means more photons per second, so more electrons per second: photocurrent increases.
$K_{max} = h\nu - \phi$ does not change with intensity.
So the answer is (a) photo-current increases.
