Figure represents the graph of kinetic energy (K) of photo electrons (in eV) and frequency (V) for Q metal used as cathode in photoelectric experiment. The work function of metal is:
A) \[1eV\]
B) \[1.5eV\]
C) \[2eV\]
D) \[3eV\]
Correct Answer:
C
Solution :
Work function is the intercept of KE axis i.e., \[2eV\].
