Assertion (A) : On increasing the frequency of light larger number of photoelectrons are emitted . Reason (R) : The number of electrons emitted depends on the intensity of incident light.

When a high frequency electromagnetic radiation is incident on a metallic surface, electrons are emitted from the surface. Energy of emitted photoelectrons depends only on the frequency of incident electromagnetic radiation and the number of emitted electrons depends only on the intensity of incident light. Einstein's protoelectron equation [K_(max)=hv-phi} correctly ecplains the PE, where upsilon= frequency of incident light and phi= work function. Q. The slope of the graph shown if Fig. [here h is the Planck's constant and e is the charge of an electron] is
