The variation of photo-current with collector potential for different frequencies of incident radiation ( v₁, v₂ ) and ( v₃ ) is as shown in the graph, then

Options

  1. A( v₁=v₂=v₃ )
  2. B( v₁>v₂>v₃ )
  3. C( v₁ < v₂ < v₃ )
  4. D( v₃= v₁+v₂ 2 )

Correct answer

C. ( v₁ < v₂ < v₃ )

Step-by-step solution

The stopping potential is directly proportional to the frequency of incident radiation and photoelectric current is independent of the frequency of incident radiation. Therefore, ( f₁ < f₂ < f₃ )
