**which of the following statements about learning is true?**

A) 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

B) 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

C) When intensity of light is increased the number of photons ejected increases but the energies of these electrons are the same

D) The plot of kinetic energy of the photoelectrons against frequency of absorbed radiation gives a straight line parallel to x-axis

**Correct Answer :**

Option (D) – The plot of kinetic energy of the photoelectrons against frequency of absorbed radiation gives a straight line parallel to x-axis
