JEE Mains · Physics · STD 12 - 11. Dual nature of radiation and matter
In a photoelectric effect experiment, the graph of stopping potential \(V\) versus reciprocal of wavelength obtained is shown in the figure. As the intensity of incident radiation is increased
- A Slope of the straight line get more steep
- B Straight line shifts to left
- C Graph does not change
- D Straight line shifts to right
Answer & Solution
Correct Answer
(C) Graph does not change
Step-by-step Solution
Detailed explanation
\(eV =\frac{ hc }{\lambda}-\phi\) \(V =\left(\frac{ hc }{ e }\right)\left(\frac{1}{\lambda}\right)-\phi\) Slope of the line in above equation and all other terms are independent of intensity. The graph does not change.
