This question has Statement 1 and Statement 2. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement 1: A metallic surface is irradiated by a monochromatic light of frequency $v>v_0$ (the threshold frequency). If the incident frequency is now doubled, the photocurrent and the maximum kinetic energy are also doubled. Statement 2: The maximum kinetic energy of photoelectrons emitted from a surface is linearly dependent on the frequency of the incident light. The photocurrent depends only on the intensity of the incident light.
  1. Statement 1 is true, Statement 2 is true, Statement 2 is the correct explanation of Statement 1.
  2. Statement 1 is false, Statement 2 is true.
  3. Statement 1 is true, Statement 2 is false.
  4. Statement 1 is true, Statement 2 is true, Statement 2 is not the correct explanation of Statement 1.

Solution

The maximum kinetic energy of photoelectrons depends upon frequency on incident light and photo current depends upon intensity of incident light.
