According to Einstein's photoelectric equation, the plot of the kinetic energy of the emitted photo electrons from a metal Vs the frequency of the incident radiation gives a straight line whose slope (a) depends both on the intensity of the radiation and the metal used (b) depends on the intensity of the radiation (c) depends on the nature of the metal used (d) is the same for all metals and independent of the intensity of the radiation

Answer: (d). KEmax = hν - φ, so slope = h, a universal constant. It does not depend on the metal (only the intercept does) or on intensity. So the answer is (d).

Photoelectric Experiment: Intensity, Stopping Potential & Graphs

According to Einstein's photoelectric equation, the plot of the kinetic energy of the emitted photo electrons from a metal $Vs$ the frequency of the incident radiation gives a straight line whose slope

Show answer and solution

Answer: (d)

$KE_{max} = h\nu - \phi$ , so slope $= h$ , a universal constant.
It does not depend on the metal (only the intercept does) or on intensity.
So the answer is (d).
