Teaching MPPSC Assistant Professor Mock Test Series 2025 Physics Dual Nature: Photon and Matter Waves The Photoelectric Effect
When a certain metal surface is illuminated with light of frequency v, the stopping potential for photoelectric current is V0. When the same surface is illuminated by light of frequency \(\frac{v}{2}\), the stopping potential is \(\frac{v_0}{4}\), the threshold frequency of photoelectric emission is
1
\(\frac{v}{6}\)
2
\(\frac{v}{3}\)
3
\(\frac{2v}{3}\)
4
\(\frac{4v}{3}\)
