According to Einstein's photoelectric equation, the graph of the kinetic energy of the emitted photoelectrons versus the frequency of incident radiation gives a straight line whose slope

Options

  1. Adepends on the intensity of incident radiation.
  2. Bdepends on the nature of the metal used.
  3. Cis the same for all metals and independent of the intensity of radiation.
  4. Ddepends on both the intensity of incident radiation and the nature of metal used.

Correct answer

C. is the same for all metals and independent of the intensity of radiation.

Step-by-step solution

According to Einstein's photoelectric equation, the maximum kinetic energy of emitted photoelectrons is given by K_ max = h - where h is Planck's constant, is the frequency of incident radiation, and is the work function of the metal. Comparing this with the equation of a straight line y = mx + c , we get the slope m = h . Since Planck's constant h is a universal constant, the slope of the graph is the same for all metals and is completely independent of the intensity of the incident radiation. Answer: is the same
