12 Physics Dual Nature Of Radiation And Matter - Set No : 8 Question No :6
Question No : 6
The
stopping potential as a function of the frequency of the incident radiation
is plotted for two different photoelectric surfaces  and  The graphs show that work function
of is |
| a) | Grater
than that of  | b) | Smaller than that of |
| c) | Equal to
that of | d) | No inference can be drawn about their work functions from the given graphs |
Answer No : 6
(b)From
the given graph it is clear that if we extend the given graph for and  intercept of the line on  axis will be smaller as compared to
line means work function of is smaller than that of |
