The threshold frequency for certain metals is v0​. When the light of frequency 2v0​ is incident on it, the maximum velocity of photoelectrons is 4×106ms−1. If the frequency of incident radiation is increased to 5v0, then the maximum velocity of photoelectrons will be : (A) 2 × 106 ms−1(B) 2 × 107 ms−1 (C) 4/5 × 106 ms−1 (D) 8 × 106 ms−1

The Einstein's equation for photoelectric effect is given by, where KE= maximum kinetic energy of electron h= Planck's constant =... View Article
