If the frequency of incident light falling on a photosensitive metal is doubled, the kinetic energy of the emitted photoelectron is
Show Hint
Doubling the frequency increases the total energy of the incoming photon. Since the "cost" to exit the metal (the work function) stays the same, all that extra energy goes directly into the electron's speed, making the final kinetic energy more than doubled.
