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 ?
NEET 2009 (Mains)

Options:

Answer:

Solution:

As a and $b$ have same stopping potential and $c$ has greater stopping potential, then $v_{c} > v_{a} = v_{b}$ as $b$ and $c$ have same saturation current and $a$ has lesser value. So $I_{a} < I_{b} = I_{c}$
