JEE Main 2012 Physics question

PhysicsDual Nature of Matter and RadiationJEE Main 2012

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 (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.

Answer: (2)

Solution

is linear in ν (not proportional), and the photocurrent depends on intensity — Statement 2
