According to Einstein's photoelectric equation, the plot of the Kinetic Energy of the emitted photoelectrons from a metal versus the frequency of the incident radiation gives a straight line whose slope:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → is the same for all metals and independent of the intensity of the radiation
The work function ($\phi$) depends on the metal and the kinetic energy is only dependent on the frequency of the incident radiation if the metal is same.
$K.E_{max}=hv-\phi$
