Photons of frequency, , fall on metal surface for which the threshold of frequency is . Then — Atomic Structure Chemistry Question

💡 Solution & Explanation

Electrons emitted in the photoelectric effect originate from different depths within the metal and undergo collisions before escaping, resulting in varying kinetic energies. The maximum kinetic energy is $h(v - v_0)$, meaning the energies range from 0 to $h(v - v_0)$. Therefore, correct answer is B.
