In the experimental setup for a photocell, the wavelength of the light incident on the cathod is initially 0.6 times the threshold wavelength for the material of the cathode. Certain change in the experimental setup are given in column A and their possibel effects are given in column B. {:("Column A","Column B"),((i)"The intensity of the incident light is doubled but the frequency remains unaltered",(a)"Photocurrent remains the same"),((ii)"Both the intensity and wavelength of the incident light are doubled",(b)"Photcurrent falls to zero"),((iii)"The intensity of the incident light is doubled and its wavelength is made half",(c)"Stopping potential increase"),((iv)"The intensity of the incident light ramains the same and the wavelength is made half",(d) "Photocurrent increases"):}
