Vedclass · Answer

(B) In the photoelectric effect,the stopping potential depends on the frequency of the incident radiation,while the saturation current depends on the intensity of the incident radiation.From the graph,curves $(a)$ and $(b)$ have the same stopping potential (the point where the curve intersects the negative x-axis),which implies they have the same frequency.However,they have different saturation currents (the plateau value of the photo current),which implies they have different intensities.Therefore,curves $(a)$ and $(b)$ represent incident radiations of the same frequency but different intensities.

The figure shows a plot of photo current versus anode potential for a photo sensitive surface for three different radiations. Which one of the following is a correct statement?
