Which of the following statements with respect to the photoelectric effect is incorrect?
A) A plot of the kinetic energy of the ejected electrons versus the frequency of the incident radiation has a slope that is equal to the value of the work function.
B) All metals have a unique work function.
C) The kinetic energy of the ejected electrons does not increase with the intensity of the incident radiation.
D) A plot of the kinetic energy of the ejected electrons versus the frequency of the incident radiation is linear.

Question

Quizplus · Accepted Answer

The slope of the plot of kinetic energy of the ejected electrons versus the frequency of the incident radiation is equal to Planck's constant (h), not the value of the work function. The work function is the y-intercept of this plot, representing the minimum energy needed to eject electrons.
