Q. Which of the following statements is not true with respect to photoelectric effect ?
A. The plot of kinetic energy of the photoelectrons against frequency of absorbed radiation gives a straight line parallel to x-axis
B. The plot of K.E. of the photoelectrons against frequency of absorbed radiation gives a straight line with slope equal to h and intercept ro
C. The plot of kinetic energy of the photoelectrons versus the intensity of incident radiation with constant frequency gives a straight line parallel to x-axis
D. When intensity of light is increased the number of photons ejected increases but the energies of these electrons are the same
Answer: The plot of kinetic energy of the photoelectrons against frequency of absorbed radiation gives a straight line parallel to x-axis
