If the intensity of monochromatic light incident on a photosensitive surface is doubled while its frequency remains unchanged and above the threshold value, how will the photocurrent–voltage curve be affected?
a) Both saturation current and stopping potential will double
b) Saturation current will remain the same but stopping potential will double
c) Saturation current will double while the stopping potential remains the same
d) Both saturation current and stopping potential will remain unchanged
