The graph between 
of ejected photoelectrons and the frequency v of incident radiation for a material exhibiting photoelectric effect is shown in the figure. The work function of the material is:
Text Solution
Verified by ExpertsThe correct answer is:
A
Using Einstein's photoelectric equation
The intercept of KE-v graph on KE axis gives the value of work function.
Hence, work function
