The stopping potential as a function of frequency of incident radiation is plotted for two different photo electric surfaces A and B. The graphs show the work function of A is
Text Solution
Verified by ExpertsThe correct answer is:
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
