Class 12PhysicsDual Nature of Radiation and matterEinstein's Photoelectric Equation and Energy Quantum of Radiation
MediumFrom a metallic surface,photoelectric emission is observed for frequencies $v_1$ and $v_2$ $(v_1 > v_2)$ of the incident light. The maximum kinetic energy of the photoelectrons emitted in the two cases are in the ratio $1:x$. Hence,the threshold frequency of the metallic surface is
- A$\frac{v_1-v_2}{x}$
- B$\frac{v_1-v_2}{x-1}$
- C$\frac{xv_1-v_2}{x-1}$
- D$\frac{xv_2-v_1}{x-1}$
