According to Einstein's photoelectric equation, the graph of KE of the photoelectron emitted from the metal versus the frequency of the incident radiation gives a straight line graph, whose slope

Options

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

Correct answer

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

Step-by-step solution

According to Einstein's photoelectric equation KE _ = hv - ₀ Comparing with the equation of straight line y=m x+c We get, slope of graph =h
