The graph shows the variation of photocurrent with the applied voltage in a photoelectric effect experiment for three different beams of light falling on identical metal surfaces, then which among the following is correct?
Options
- AA and B recieve the light of the same intensity while B & C receive the light of the same frequency
- BB and C recieve the light of the same intensity while A & B recieve the light of the same frequency
- CA & B recieve the light of the same frequency while B & C recieve the light of the same intensity
- DA and C recieve the light of the same intensity and B & C recieve the light of the same frequency
Correct answer
A. A and B recieve the light of the same intensity while B & C receive the light of the same frequency
Step-by-step solution
Saturation current for A and B Incident light will have the same intensity while stopping potential is same for B and C e V s = K m a x = h ν - ϕ Frequency of incident light will be the same
