Question
In an experiment on photoelectric effect the frequency f of the incident light is plotted against the stopping potential null. The work function of the photoelectric surface is given by (e is electronic charge)
- OB nulle in eV
- OB in volt
- OA in eV
- The slope of the line AB
The correct answer is: OB nulle in eV
Using Einstein’s equation, null
Comparing this equation with null
We get intercept on – V0 axis null
Þ null Þ null
